+Blackfriday
+===========
+
+Blackfriday is a [Markdown][1] processor implemented in [Go][2]. It
+is paranoid about its input (so you can safely feed it user-supplied
+data), it is fast, it supports common extensions (tables, smart
+punctuation substitutions, etc.), and it is safe for all utf-8
+(unicode) input.
+
+HTML output is currently supported, along with Smartypants
+extensions. An experimental LaTeX output engine is also included.
+
+It started as a translation from C of [upskirt][3].
+
+
+Installation
+------------
+
+Blackfriday is compatible with Go 1. If you are using an older
+release of Go, consider using v1.1 of blackfriday, which was based
+on the last stable release of Go prior to Go 1. You can find it as a
+tagged commit on github.
+
+With Go 1 and git installed:
+
+    go get github.com/russross/blackfriday
+
+will download, compile, and install the package into your `$GOPATH`
+directory hierarchy. Alternatively, you can import it into a
+project:
+
+    import "github.com/russross/blackfriday"
+
+and when you build that project with `go build`, blackfriday will be
+downloaded and installed automatically.
+
+Usage
+-----
+
+For basic usage, it is as simple as getting your input into a byte
+slice and calling:
+
+    output := blackfriday.MarkdownBasic(input)
+
+This renders it with no extensions enabled. To get a more useful
+feature set, use this instead:
+
+    output := blackfriday.MarkdownCommon(input)
+
+If you want to customize the set of options, first get a renderer
+(currently either the HTML or LaTeX output engines), then use it to
+call the more general `Markdown` function. For examples, see the
+implementations of `MarkdownBasic` and `MarkdownCommon` in
+`markdown.go`.
+
+You can also check out `blackfriday-tool` for a more complete example
+of how to use it. Download and install it using:
+
+    go get github.com/russross/blackfriday-tool
+
+This is a simple command-line tool that allows you to process a
+markdown file using a standalone program.  You can also browse the
+source directly on github if you are just looking for some example
+code:
+
+* <http://github.com/russross/blackfriday-tool>
+
+Note that if you have not already done so, installing
+`blackfriday-tool` will be sufficient to download and install
+blackfriday in addition to the tool itself. The tool binary will be
+installed in `$GOPATH/bin`.  This is a statically-linked binary that
+can be copied to wherever you need it without worrying about
+dependencies and library versions.
+
+
+Features
+--------
+
+All features of upskirt are supported, including:
+
+*   **Compatibility**. The Markdown v1.0.3 test suite passes with
+    the `--tidy` option.  Without `--tidy`, the differences are
+    mostly in whitespace and entity escaping, where blackfriday is
+    more consistent and cleaner.
+
+*   **Common extensions**, including table support, fenced code
+    blocks, autolinks, strikethroughs, non-strict emphasis, etc.
+
+*   **Safety**. Blackfriday is paranoid when parsing, making it safe
+    to feed untrusted user input without fear of bad things
+    happening. The test suite stress tests this and there are no
+    known inputs that make it crash.  If you find one, please let me
+    know and send me the input that does it.
+
+    NOTE: "safety" in this context means *runtime safety only*. It is
+    not bullet proof against JavaScript injections, though we're working
+    on it (https://github.com/russross/blackfriday/issues/11 tracks the
+    progress).
+
+*   **Fast processing**. It is fast enough to render on-demand in
+    most web applications without having to cache the output.
+
+*   **Thread safety**. You can run multiple parsers in different
+    goroutines without ill effect. There is no dependence on global
+    shared state.
+
+*   **Minimal dependencies**. Blackfriday only depends on standard
+    library packages in Go. The source code is pretty
+    self-contained, so it is easy to add to any project, including
+    Google App Engine projects.
+
+*   **Standards compliant**. Output successfully validates using the
+    W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
+
+
+Extensions
+----------
+
+In addition to the standard markdown syntax, this package
+implements the following extensions:
+
+*   **Intra-word emphasis supression**. The `_` character is
+    commonly used inside words when discussing code, so having
+    markdown interpret it as an emphasis command is usually the
+    wrong thing. Blackfriday lets you treat all emphasis markers as
+    normal characters when they occur inside a word.
+
+*   **Tables**. Tables can be created by drawing them in the input
+    using a simple syntax:
+
+    ```
+    Name    | Age
+    --------|------
+    Bob     | 27
+    Alice   | 23
+    ```
+
+*   **Fenced code blocks**. In addition to the normal 4-space
+    indentation to mark code blocks, you can explicitly mark them
+    and supply a language (to make syntax highlighting simple). Just
+    mark it like this:
+
+        ``` go
+        func getTrue() bool {
+            return true
+        }
+        ```
+
+    You can use 3 or more backticks to mark the beginning of the
+    block, and the same number to mark the end of the block.
+
+*   **Autolinking**. Blackfriday can find URLs that have not been
+    explicitly marked as links and turn them into links.
+
+*   **Strikethrough**. Use two tildes (`~~`) to mark text that
+    should be crossed out.
+
+*   **Hard line breaks**. With this extension enabled (it is off by
+    default in the `MarkdownBasic` and `MarkdownCommon` convenience
+    functions), newlines in the input translate into line breaks in
+    the output.
+
+*   **Smart quotes**. Smartypants-style punctuation substitution is
+    supported, turning normal double- and single-quote marks into
+    curly quotes, etc.
+
+*   **LaTeX-style dash parsing** is an additional option, where `--`
+    is translated into `&ndash;`, and `---` is translated into
+    `&mdash;`. This differs from most smartypants processors, which
+    turn a single hyphen into an ndash and a double hyphen into an
+    mdash.
+
+*   **Smart fractions**, where anything that looks like a fraction
+    is translated into suitable HTML (instead of just a few special
+    cases like most smartypant processors). For example, `4/5`
+    becomes `<sup>4</sup>&frasl;<sub>5</sub>`, which renders as
+    <sup>4</sup>&frasl;<sub>5</sub>.
+
+
+Other renderers
+---------------
+
+Blackfriday is structured to allow alternative rendering engines. Here
+are a few of note:
+
+*   [github_flavored_markdown](https://godoc.org/github.com/shurcooL/go/github_flavored_markdown):
+    provides a GitHub Flavored Markdown renderer with fenced code block
+    highlighting, clickable header anchor links.
+
+    It's not customizable, and its goal is to produce HTML output
+    equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode),
+    except the rendering is performed locally.
+
+*   [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
+    but for markdown.
+
+*   LaTeX output: renders output as LaTeX. This is currently part of the
+    main Blackfriday repository, but may be split into its own project
+    in the future. If you are interested in owning and maintaining the
+    LaTeX output component, please be in touch.
+
+    It renders some basic documents, but is only experimental at this
+    point. In particular, it does not do any inline escaping, so input
+    that happens to look like LaTeX code will be passed through without
+    modification.
+
+
+Todo
+----
+
+*   More unit testing
+*   Markdown pretty-printer output engine
+*   Improve unicode support. It does not understand all unicode
+    rules (about what constitutes a letter, a punctuation symbol,
+    etc.), so it may fail to detect word boundaries correctly in
+    some instances. It is safe on all utf-8 input.

+<h2>Getting the Gist of Markdown's Formatting Syntax</h2>
+
+<p>This page offers a brief overview of what it's like to use Markdown.
+The <a href="/projects/markdown/syntax" title="Markdown Syntax">syntax page</a> provides complete, detailed documentation for
+every feature, but Markdown should be very easy to pick up simply by
+looking at a few examples of it in action. The examples on this page
+are written in a before/after style, showing example syntax and the
+HTML output produced by Markdown.</p>
+
+<p>It's also helpful to simply try Markdown out; the <a href="/projects/markdown/dingus" title="Markdown Dingus">Dingus</a> is a
+web application that allows you type your own Markdown-formatted text
+and translate it to XHTML.</p>
+
+<p><strong>Note:</strong> This document is itself written using Markdown; you
+can <a href="/projects/markdown/basics.text">see the source for it by adding '.text' to the URL</a>.</p>
+
+<h2>Paragraphs, Headers, Blockquotes</h2>
+
+<p>A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.</p>
+
+<p>Markdown offers two styles of headers: <em>Setext</em> and <em>atx</em>.
+Setext-style headers for <code>&lt;h1&gt;</code> and <code>&lt;h2&gt;</code> are created by
+&quot;underlining&quot; with equal signs (<code>=</code>) and hyphens (<code>-</code>), respectively.
+To create an atx-style header, you put 1-6 hash marks (<code>#</code>) at the
+beginning of the line -- the number of hashes equals the resulting
+HTML header level.</p>
+
+<p>Blockquotes are indicated using email-style '<code>&gt;</code>' angle brackets.</p>
+
+<p>Markdown:</p>
+
+<pre><code>A First Level Header
+====================
+
+A Second Level Header
+---------------------
+
+Now is the time for all good men to come to
+the aid of their country. This is just a
+regular paragraph.
+
+The quick brown fox jumped over the lazy
+dog's back.
+
+### Header 3
+
+&gt; This is a blockquote.
+&gt; 
+&gt; This is the second paragraph in the blockquote.
+&gt;
+&gt; ## This is an H2 in a blockquote
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;h1&gt;A First Level Header&lt;/h1&gt;
+
+&lt;h2&gt;A Second Level Header&lt;/h2&gt;
+
+&lt;p&gt;Now is the time for all good men to come to
+the aid of their country. This is just a
+regular paragraph.&lt;/p&gt;
+
+&lt;p&gt;The quick brown fox jumped over the lazy
+dog's back.&lt;/p&gt;
+
+&lt;h3&gt;Header 3&lt;/h3&gt;
+
+&lt;blockquote&gt;
+    &lt;p&gt;This is a blockquote.&lt;/p&gt;
+
+    &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;
+
+    &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
+&lt;/blockquote&gt;
+</code></pre>
+
+<h3>Phrase Emphasis</h3>
+
+<p>Markdown uses asterisks and underscores to indicate spans of emphasis.</p>
+
+<p>Markdown:</p>
+
+<pre><code>Some of these words *are emphasized*.
+Some of these words _are emphasized also_.
+
+Use two asterisks for **strong emphasis**.
+Or, if you prefer, __use two underscores instead__.
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
+Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;
+
+&lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
+Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
+</code></pre>
+
+<h2>Lists</h2>
+
+<p>Unordered (bulleted) lists use asterisks, pluses, and hyphens (<code>*</code>,
+<code>+</code>, and <code>-</code>) as list markers. These three markers are
+interchangable; this:</p>
+
+<pre><code>*   Candy.
+*   Gum.
+*   Booze.
+</code></pre>
+
+<p>this:</p>
+
+<pre><code>+   Candy.
++   Gum.
++   Booze.
+</code></pre>
+
+<p>and this:</p>
+
+<pre><code>-   Candy.
+-   Gum.
+-   Booze.
+</code></pre>
+
+<p>all produce the same output:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;Candy.&lt;/li&gt;
+&lt;li&gt;Gum.&lt;/li&gt;
+&lt;li&gt;Booze.&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<p>Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:</p>
+
+<pre><code>1.  Red
+2.  Green
+3.  Blue
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;ol&gt;
+&lt;li&gt;Red&lt;/li&gt;
+&lt;li&gt;Green&lt;/li&gt;
+&lt;li&gt;Blue&lt;/li&gt;
+&lt;/ol&gt;
+</code></pre>
+
+<p>If you put blank lines between items, you'll get <code>&lt;p&gt;</code> tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:</p>
+
+<pre><code>*   A list item.
+
+    With multiple paragraphs.
+
+*   Another item in the list.
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
+&lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
+&lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<h3>Links</h3>
+
+<p>Markdown supports two styles for creating links: <em>inline</em> and
+<em>reference</em>. With both styles, you use square brackets to delimit the
+text you want to turn into a link.</p>
+
+<p>Inline-style links use parentheses immediately after the link text.
+For example:</p>
+
+<pre><code>This is an [example link](http://example.com/).
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;This is an &lt;a href=&quot;http://example.com/&quot;&gt;
+example link&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>Optionally, you may include a title attribute in the parentheses:</p>
+
+<pre><code>This is an [example link](http://example.com/ &quot;With a Title&quot;).
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;This is an &lt;a href=&quot;http://example.com/&quot; title=&quot;With a Title&quot;&gt;
+example link&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:</p>
+
+<pre><code>I get 10 times more traffic from [Google][1] than from
+[Yahoo][2] or [MSN][3].
+
+[1]: http://google.com/        &quot;Google&quot;
+[2]: http://search.yahoo.com/  &quot;Yahoo Search&quot;
+[3]: http://search.msn.com/    &quot;MSN Search&quot;
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;I get 10 times more traffic from &lt;a href=&quot;http://google.com/&quot;
+title=&quot;Google&quot;&gt;Google&lt;/a&gt; than from &lt;a href=&quot;http://search.yahoo.com/&quot;
+title=&quot;Yahoo Search&quot;&gt;Yahoo&lt;/a&gt; or &lt;a href=&quot;http://search.msn.com/&quot;
+title=&quot;MSN Search&quot;&gt;MSN&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are <em>not</em> case sensitive:</p>
+
+<pre><code>I start my morning with a cup of coffee and
+[The New York Times][NY Times].
+
+[ny times]: http://www.nytimes.com/
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;I start my morning with a cup of coffee and
+&lt;a href=&quot;http://www.nytimes.com/&quot;&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<h3>Images</h3>
+
+<p>Image syntax is very much like link syntax.</p>
+
+<p>Inline (titles are optional):</p>
+
+<pre><code>![alt text](/path/to/img.jpg &quot;Title&quot;)
+</code></pre>
+
+<p>Reference-style:</p>
+
+<pre><code>![alt text][id]
+
+[id]: /path/to/img.jpg &quot;Title&quot;
+</code></pre>
+
+<p>Both of the above examples produce the same output:</p>
+
+<pre><code>&lt;img src=&quot;/path/to/img.jpg&quot; alt=&quot;alt text&quot; title=&quot;Title&quot; /&gt;
+</code></pre>
+
+<h3>Code</h3>
+
+<p>In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (<code>&amp;</code>) and angle brackets (<code>&lt;</code> or
+<code>&gt;</code>) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:</p>
+
+<pre><code>I strongly recommend against using any `&lt;blink&gt;` tags.
+
+I wish SmartyPants used named entities like `&amp;mdash;`
+instead of decimal-encoded entites like `&amp;#8212;`.
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;I strongly recommend against using any
+&lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
+
+&lt;p&gt;I wish SmartyPants used named entities like
+&lt;code&gt;&amp;amp;mdash;&lt;/code&gt; instead of decimal-encoded
+entites like &lt;code&gt;&amp;amp;#8212;&lt;/code&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>To specify an entire block of pre-formatted code, indent every line of
+the block by 4 spaces or 1 tab. Just like with code spans, <code>&amp;</code>, <code>&lt;</code>,
+and <code>&gt;</code> characters will be escaped automatically.</p>
+
+<p>Markdown:</p>
+
+<pre><code>If you want your page to validate under XHTML 1.0 Strict,
+you've got to put paragraph tags in your blockquotes:
+
+    &lt;blockquote&gt;
+        &lt;p&gt;For example.&lt;/p&gt;
+    &lt;/blockquote&gt;
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;If you want your page to validate under XHTML 1.0 Strict,
+you've got to put paragraph tags in your blockquotes:&lt;/p&gt;
+
+&lt;pre&gt;&lt;code&gt;&amp;lt;blockquote&amp;gt;
+    &amp;lt;p&amp;gt;For example.&amp;lt;/p&amp;gt;
+&amp;lt;/blockquote&amp;gt;
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>

+
+This page offers a brief overview of what it's like to use Markdown.
+The [syntax page] [s] provides complete, detailed documentation for

+    > 
+    > This is the second paragraph in the blockquote.
+    >

+
+
+Output:
+
+    <h1>A First Level Header</h1>
+    
+    <h2>A Second Level Header</h2>
+    
+    <p>Now is the time for all good men to come to
+    the aid of their country. This is just a

+    
+    <p>The quick brown fox jumped over the lazy

+    
+    <h3>Header 3</h3>
+    
+    <blockquote>
+        <p>This is a blockquote.</p>
+        
+        <p>This is the second paragraph in the blockquote.</p>
+        
+        <h2>This is an H2 in a blockquote</h2>
+    </blockquote>
+
+
+
+### Phrase Emphasis ###
+
+Markdown uses asterisks and underscores to indicate spans of emphasis.
+
+Markdown:
+
+    Some of these words *are emphasized*.
+    Some of these words _are emphasized also_.
+    
+    Use two asterisks for **strong emphasis**.
+    Or, if you prefer, __use two underscores instead__.
+
+Output:
+
+    <p>Some of these words <em>are emphasized</em>.
+    Some of these words <em>are emphasized also</em>.</p>
+    
+    <p>Use two asterisks for <strong>strong emphasis</strong>.
+    Or, if you prefer, <strong>use two underscores instead</strong>.</p>
+   
+
+
+## Lists ##
+
+Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
+`+`, and `-`) as list markers. These three markers are
+interchangable; this:
+
+    *   Candy.
+    *   Gum.
+    *   Booze.
+
+this:
+
+    +   Candy.
+    +   Gum.
+    +   Booze.
+
+and this:
+
+    -   Candy.
+    -   Gum.
+    -   Booze.
+
+all produce the same output:
+
+    <ul>
+    <li>Candy.</li>
+    <li>Gum.</li>
+    <li>Booze.</li>
+    </ul>
+
+Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:
+
+    1.  Red
+    2.  Green
+    3.  Blue
+
+Output:
+
+    <ol>
+    <li>Red</li>
+    <li>Green</li>
+    <li>Blue</li>
+    </ol>
+
+If you put blank lines between items, you'll get `<p>` tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:
+
+    *   A list item.
+    
+        With multiple paragraphs.
+
+    *   Another item in the list.
+
+Output:
+
+    <ul>
+    <li><p>A list item.</p>
+    <p>With multiple paragraphs.</p></li>
+    <li><p>Another item in the list.</p></li>
+    </ul>
+    
+
+
+### Links ###
+
+Markdown supports two styles for creating links: *inline* and
+*reference*. With both styles, you use square brackets to delimit the
+text you want to turn into a link.
+
+Inline-style links use parentheses immediately after the link text.
+For example:
+
+    This is an [example link](http://example.com/).
+
+Output:
+
+    <p>This is an <a href="http://example.com/">
+    example link</a>.</p>
+
+Optionally, you may include a title attribute in the parentheses:
+
+    This is an [example link](http://example.com/ "With a Title").
+
+Output:
+
+    <p>This is an <a href="http://example.com/" title="With a Title">
+    example link</a>.</p>
+
+Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:
+
+    I get 10 times more traffic from [Google][1] than from
+    [Yahoo][2] or [MSN][3].
+
+    [1]: http://google.com/        "Google"
+    [2]: http://search.yahoo.com/  "Yahoo Search"
+    [3]: http://search.msn.com/    "MSN Search"
+
+Output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from <a href="http://search.yahoo.com/"
+    title="Yahoo Search">Yahoo</a> or <a href="http://search.msn.com/"
+    title="MSN Search">MSN</a>.</p>
+
+The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are *not* case sensitive:
+
+    I start my morning with a cup of coffee and
+    [The New York Times][NY Times].
+
+    [ny times]: http://www.nytimes.com/
+
+Output:
+
+    <p>I start my morning with a cup of coffee and
+    <a href="http://www.nytimes.com/">The New York Times</a>.</p>
+
+
+### Images ###
+
+Image syntax is very much like link syntax.
+
+Inline (titles are optional):
+
+    ![alt text](/path/to/img.jpg "Title")
+
+Reference-style:
+
+    ![alt text][id]
+
+    [id]: /path/to/img.jpg "Title"
+
+Both of the above examples produce the same output:
+
+    <img src="/path/to/img.jpg" alt="alt text" title="Title" />
+
+
+
+### Code ###
+
+In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (`&`) and angle brackets (`<` or
+`>`) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:
+
+    I strongly recommend against using any `<blink>` tags.
+
+    I wish SmartyPants used named entities like `&mdash;`
+    instead of decimal-encoded entites like `&#8212;`.
+
+Output:
+
+    <p>I strongly recommend against using any
+    <code>&lt;blink&gt;</code> tags.</p>
+    
+    <p>I wish SmartyPants used named entities like
+    <code>&amp;mdash;</code> instead of decimal-encoded
+    entites like <code>&amp;#8212;</code>.</p>
+
+
+To specify an entire block of pre-formatted code, indent every line of
+the block by 4 spaces or 1 tab. Just like with code spans, `&`, `<`,
+and `>` characters will be escaped automatically.
+
+Markdown:
+
+    If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:
+
+        <blockquote>
+            <p>For example.</p>
+        </blockquote>

+<h2 id="overview">Overview</h2>
+
+<h3 id="philosophy">Philosophy</h3>
+
+<p>Markdown is intended to be as easy-to-read and easy-to-write as is feasible.</p>
+
+<p>Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including <a href="http://docutils.sourceforge.net/mirror/setext.html">Setext</a>, <a href="http://www.aaronsw.com/2002/atx/">atx</a>, <a href="http://textism.com/tools/textile/">Textile</a>, <a href="http://docutils.sourceforge.net/rst.html">reStructuredText</a>,
+<a href="http://www.triptico.com/software/grutatxt.html">Grutatext</a>, and <a href="http://ettext.taint.org/doc/">EtText</a> -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.</p>
+
+<p>To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like *emphasis*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.</p>
+
+<h3 id="html">Inline HTML</h3>
+
+<p>Markdown's syntax is intended for one purpose: to be used as a
+format for <em>writing</em> for the web.</p>
+
+<p>Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is <em>not</em> to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a <em>publishing</em> format; Markdown is a <em>writing</em>
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.</p>
+
+<p>For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.</p>
+
+<p>The only restrictions are that block-level HTML elements -- e.g. <code>&lt;div&gt;</code>,
+<code>&lt;table&gt;</code>, <code>&lt;pre&gt;</code>, <code>&lt;p&gt;</code>, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) <code>&lt;p&gt;</code> tags around HTML block-level tags.</p>
+
+<p>For example, to add an HTML table to a Markdown article:</p>
+
+<pre><code>This is a regular paragraph.
+
+&lt;table&gt;
+    &lt;tr&gt;
+        &lt;td&gt;Foo&lt;/td&gt;
+    &lt;/tr&gt;
+&lt;/table&gt;
+
+This is another regular paragraph.
+</code></pre>
+
+<p>Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style <code>*emphasis*</code> inside an
+HTML block.</p>
+
+<p>Span-level HTML tags -- e.g. <code>&lt;span&gt;</code>, <code>&lt;cite&gt;</code>, or <code>&lt;del&gt;</code> -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML <code>&lt;a&gt;</code> or <code>&lt;img&gt;</code> tags instead of Markdown's
+link or image syntax, go right ahead.</p>
+
+<p>Unlike block-level HTML tags, Markdown syntax <em>is</em> processed within
+span-level tags.</p>
+
+<h3 id="autoescape">Automatic Escaping for Special Characters</h3>
+
+<p>In HTML, there are two characters that demand special treatment: <code>&lt;</code>
+and <code>&amp;</code>. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. <code>&amp;lt;</code>, and
+<code>&amp;amp;</code>.</p>
+
+<p>Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&amp;T', you need to write '<code>AT&amp;amp;T</code>'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:</p>
+
+<pre><code>http://images.google.com/images?num=30&amp;q=larry+bird
+</code></pre>
+
+<p>you need to encode the URL as:</p>
+
+<pre><code>http://images.google.com/images?num=30&amp;amp;q=larry+bird
+</code></pre>
+
+<p>in your anchor tag <code>href</code> attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.</p>
+
+<p>Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into <code>&amp;amp;</code>.</p>
+
+<p>So, if you want to include a copyright symbol in your article, you can write:</p>
+
+<pre><code>&amp;copy;
+</code></pre>
+
+<p>and Markdown will leave it alone. But if you write:</p>
+
+<pre><code>AT&amp;T
+</code></pre>
+
+<p>Markdown will translate it to:</p>
+
+<pre><code>AT&amp;amp;T
+</code></pre>
+
+<p>Similarly, because Markdown supports <a href="#html">inline HTML</a>, if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:</p>
+
+<pre><code>4 &lt; 5
+</code></pre>
+
+<p>Markdown will translate it to:</p>
+
+<pre><code>4 &amp;lt; 5
+</code></pre>
+
+<p>However, inside Markdown code spans and blocks, angle brackets and
+ampersands are <em>always</em> encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single <code>&lt;</code>
+and <code>&amp;</code> in your example code needs to be escaped.)</p>
+
+<hr>
+
+<h2 id="block">Block Elements</h2>
+
+<h3 id="p">Paragraphs and Line Breaks</h3>
+
+<p>A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.</p>
+
+<p>The implication of the &quot;one or more consecutive lines of text&quot; rule is
+that Markdown supports &quot;hard-wrapped&quot; text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's &quot;Convert Line Breaks&quot; option) which translate every line break
+character in a paragraph into a <code>&lt;br /&gt;</code> tag.</p>
+
+<p>When you <em>do</em> want to insert a <code>&lt;br /&gt;</code> break tag using Markdown, you
+end a line with two or more spaces, then type return.</p>
+
+<p>Yes, this takes a tad more effort to create a <code>&lt;br /&gt;</code>, but a simplistic
+&quot;every line break is a <code>&lt;br /&gt;</code>&quot; rule wouldn't work for Markdown.
+Markdown's email-style <a href="#blockquote">blockquoting</a> and multi-paragraph <a href="#list">list items</a>
+work best -- and look better -- when you format them with hard breaks.</p>
+
+<h3 id="header">Headers</h3>
+
+<p>Markdown supports two styles of headers, <a href="http://docutils.sourceforge.net/mirror/setext.html">Setext</a> and <a href="http://www.aaronsw.com/2002/atx/">atx</a>.</p>
+
+<p>Setext-style headers are &quot;underlined&quot; using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:</p>
+
+<pre><code>This is an H1
+=============
+
+This is an H2
+-------------
+</code></pre>
+
+<p>Any number of underlining <code>=</code>'s or <code>-</code>'s will work.</p>
+
+<p>Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:</p>
+
+<pre><code># This is an H1
+
+## This is an H2
+
+###### This is an H6
+</code></pre>
+
+<p>Optionally, you may &quot;close&quot; atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :</p>
+
+<pre><code># This is an H1 #
+
+## This is an H2 ##
+
+### This is an H3 ######
+</code></pre>
+
+<h3 id="blockquote">Blockquotes</h3>
+
+<p>Markdown uses email-style <code>&gt;</code> characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a <code>&gt;</code> before every line:</p>
+
+<pre><code>&gt; This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+&gt; consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+&gt; Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+&gt; 
+&gt; Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+&gt; id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>Markdown allows you to be lazy and only put the <code>&gt;</code> before the first
+line of a hard-wrapped paragraph:</p>
+
+<pre><code>&gt; This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+&gt; Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of <code>&gt;</code>:</p>
+
+<pre><code>&gt; This is the first level of quoting.
+&gt;
+&gt; &gt; This is nested blockquote.
+&gt;
+&gt; Back to the first level.
+</code></pre>
+
+<p>Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:</p>
+
+<pre><code>&gt; ## This is a header.
+&gt; 
+&gt; 1.   This is the first list item.
+&gt; 2.   This is the second list item.
+&gt; 
+&gt; Here's some example code:
+&gt; 
+&gt;     return shell_exec(&quot;echo $input | $markdown_script&quot;);
+</code></pre>
+
+<p>Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.</p>
+
+<h3 id="list">Lists</h3>
+
+<p>Markdown supports ordered (numbered) and unordered (bulleted) lists.</p>
+
+<p>Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:</p>
+
+<pre><code>*   Red
+*   Green
+*   Blue
+</code></pre>
+
+<p>is equivalent to:</p>
+
+<pre><code>+   Red
++   Green
++   Blue
+</code></pre>
+
+<p>and:</p>
+
+<pre><code>-   Red
+-   Green
+-   Blue
+</code></pre>
+
+<p>Ordered lists use numbers followed by periods:</p>
+
+<pre><code>1.  Bird
+2.  McHale
+3.  Parish
+</code></pre>
+
+<p>It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:</p>
+
+<pre><code>&lt;ol&gt;
+&lt;li&gt;Bird&lt;/li&gt;
+&lt;li&gt;McHale&lt;/li&gt;
+&lt;li&gt;Parish&lt;/li&gt;
+&lt;/ol&gt;
+</code></pre>
+
+<p>If you instead wrote the list in Markdown like this:</p>
+
+<pre><code>1.  Bird
+1.  McHale
+1.  Parish
+</code></pre>
+
+<p>or even:</p>
+
+<pre><code>3. Bird
+1. McHale
+8. Parish
+</code></pre>
+
+<p>you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.</p>
+
+<p>If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.</p>
+
+<p>List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.</p>
+
+<p>To make lists look nice, you can wrap items with hanging indents:</p>
+
+<pre><code>*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>But if you want to be lazy, you don't have to:</p>
+
+<pre><code>*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+Suspendisse id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>If list items are separated by blank lines, Markdown will wrap the
+items in <code>&lt;p&gt;</code> tags in the HTML output. For example, this input:</p>
+
+<pre><code>*   Bird
+*   Magic
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;Bird&lt;/li&gt;
+&lt;li&gt;Magic&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<p>But this:</p>
+
+<pre><code>*   Bird
+
+*   Magic
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;&lt;p&gt;Bird&lt;/p&gt;&lt;/li&gt;
+&lt;li&gt;&lt;p&gt;Magic&lt;/p&gt;&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<p>List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be intended by either 4 spaces
+or one tab:</p>
+
+<pre><code>1.  This is a list item with two paragraphs. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+    mi posuere lectus.
+
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+    vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+    sit amet velit.
+
+2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:</p>
+
+<pre><code>*   This is a list item with two paragraphs.
+
+    This is the second paragraph in the list item. You're
+only required to indent the first line. Lorem ipsum dolor
+sit amet, consectetuer adipiscing elit.
+
+*   Another item in the same list.
+</code></pre>
+
+<p>To put a blockquote within a list item, the blockquote's <code>&gt;</code>
+delimiters need to be indented:</p>
+
+<pre><code>*   A list item with a blockquote:
+
+    &gt; This is a blockquote
+    &gt; inside a list item.
+</code></pre>
+
+<p>To put a code block within a list item, the code block needs
+to be indented <em>twice</em> -- 8 spaces or two tabs:</p>
+
+<pre><code>*   A list item with a code block:
+
+        &lt;code goes here&gt;
+</code></pre>
+
+<p>It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:</p>
+
+<pre><code>1986. What a great season.
+</code></pre>
+
+<p>In other words, a <em>number-period-space</em> sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:</p>
+
+<pre><code>1986\. What a great season.
+</code></pre>
+
+<h3 id="precode">Code Blocks</h3>
+
+<p>Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both <code>&lt;pre&gt;</code> and <code>&lt;code&gt;</code> tags.</p>
+
+<p>To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:</p>
+
+<pre><code>This is a normal paragraph:
+
+    This is a code block.
+</code></pre>
+
+<p>Markdown will generate:</p>
+
+<pre><code>&lt;p&gt;This is a normal paragraph:&lt;/p&gt;
+
+&lt;pre&gt;&lt;code&gt;This is a code block.
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>
+
+<p>One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:</p>
+
+<pre><code>Here is an example of AppleScript:
+
+    tell application &quot;Foo&quot;
+        beep
+    end tell
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;p&gt;Here is an example of AppleScript:&lt;/p&gt;
+
+&lt;pre&gt;&lt;code&gt;tell application &quot;Foo&quot;
+    beep
+end tell
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>
+
+<p>A code block continues until it reaches a line that is not indented
+(or the end of the article).</p>
+
+<p>Within a code block, ampersands (<code>&amp;</code>) and angle brackets (<code>&lt;</code> and <code>&gt;</code>)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:</p>
+
+<pre><code>    &lt;div class=&quot;footer&quot;&gt;
+        &amp;copy; 2004 Foo Corporation
+    &lt;/div&gt;
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;pre&gt;&lt;code&gt;&amp;lt;div class=&quot;footer&quot;&amp;gt;
+    &amp;amp;copy; 2004 Foo Corporation
+&amp;lt;/div&amp;gt;
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>
+
+<p>Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.</p>
+
+<h3 id="hr">Horizontal Rules</h3>
+
+<p>You can produce a horizontal rule tag (<code>&lt;hr /&gt;</code>) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:</p>
+
+<pre><code>* * *
+
+***
+
+*****
+
+- - -
+
+---------------------------------------
+
+_ _ _
+</code></pre>
+
+<hr>
+
+<h2 id="span">Span Elements</h2>
+
+<h3 id="link">Links</h3>
+
+<p>Markdown supports two style of links: <em>inline</em> and <em>reference</em>.</p>
+
+<p>In both styles, the link text is delimited by [square brackets].</p>
+
+<p>To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an <em>optional</em>
+title for the link, surrounded in quotes. For example:</p>
+
+<pre><code>This is [an example](http://example.com/ &quot;Title&quot;) inline link.
+
+[This link](http://example.net/) has no title attribute.
+</code></pre>
+
+<p>Will produce:</p>
+
+<pre><code>&lt;p&gt;This is &lt;a href=&quot;http://example.com/&quot; title=&quot;Title&quot;&gt;
+an example&lt;/a&gt; inline link.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://example.net/&quot;&gt;This link&lt;/a&gt; has no
+title attribute.&lt;/p&gt;
+</code></pre>
+
+<p>If you're referring to a local resource on the same server, you can
+use relative paths:</p>
+
+<pre><code>See my [About](/about/) page for details.
+</code></pre>
+
+<p>Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:</p>
+
+<pre><code>This is [an example][id] reference-style link.
+</code></pre>
+
+<p>You can optionally use a space to separate the sets of brackets:</p>
+
+<pre><code>This is [an example] [id] reference-style link.
+</code></pre>
+
+<p>Then, anywhere in the document, you define your link label like this,
+on a line by itself:</p>
+
+<pre><code>[id]: http://example.com/  &quot;Optional Title Here&quot;
+</code></pre>
+
+<p>That is:</p>
+
+<ul>
+<li>Square brackets containing the link identifier (optionally
+indented from the left margin using up to three spaces);</li>
+<li>followed by a colon;</li>
+<li>followed by one or more spaces (or tabs);</li>
+<li>followed by the URL for the link;</li>
+<li>optionally followed by a title attribute for the link, enclosed
+in double or single quotes.</li>
+</ul>
+
+<p>The link URL may, optionally, be surrounded by angle brackets:</p>
+
+<pre><code>[id]: &lt;http://example.com/&gt;  &quot;Optional Title Here&quot;
+</code></pre>
+
+<p>You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:</p>
+
+<pre><code>[id]: http://example.com/longish/path/to/resource/here
+    &quot;Optional Title Here&quot;
+</code></pre>
+
+<p>Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.</p>
+
+<p>Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are <em>not</em> case sensitive. E.g. these two links:</p>
+
+<pre><code>[link text][a]
+[link text][A]
+</code></pre>
+
+<p>are equivalent.</p>
+
+<p>The <em>implicit link name</em> shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+&quot;Google&quot; to the google.com web site, you could simply write:</p>
+
+<pre><code>[Google][]
+</code></pre>
+
+<p>And then define the link:</p>
+
+<pre><code>[Google]: http://google.com/
+</code></pre>
+
+<p>Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:</p>
+
+<pre><code>Visit [Daring Fireball][] for more information.
+</code></pre>
+
+<p>And then define the link:</p>
+
+<pre><code>[Daring Fireball]: http://daringfireball.net/
+</code></pre>
+
+<p>Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.</p>
+
+<p>Here's an example of reference links in action:</p>
+
+<pre><code>I get 10 times more traffic from [Google] [1] than from
+[Yahoo] [2] or [MSN] [3].
+
+  [1]: http://google.com/        &quot;Google&quot;
+  [2]: http://search.yahoo.com/  &quot;Yahoo Search&quot;
+  [3]: http://search.msn.com/    &quot;MSN Search&quot;
+</code></pre>
+
+<p>Using the implicit link name shortcut, you could instead write:</p>
+
+<pre><code>I get 10 times more traffic from [Google][] than from
+[Yahoo][] or [MSN][].
+
+  [google]: http://google.com/        &quot;Google&quot;
+  [yahoo]:  http://search.yahoo.com/  &quot;Yahoo Search&quot;
+  [msn]:    http://search.msn.com/    &quot;MSN Search&quot;
+</code></pre>
+
+<p>Both of the above examples will produce the following HTML output:</p>
+
+<pre><code>&lt;p&gt;I get 10 times more traffic from &lt;a href=&quot;http://google.com/&quot;
+title=&quot;Google&quot;&gt;Google&lt;/a&gt; than from
+&lt;a href=&quot;http://search.yahoo.com/&quot; title=&quot;Yahoo Search&quot;&gt;Yahoo&lt;/a&gt;
+or &lt;a href=&quot;http://search.msn.com/&quot; title=&quot;MSN Search&quot;&gt;MSN&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>For comparison, here is the same paragraph written using
+Markdown's inline link style:</p>
+
+<pre><code>I get 10 times more traffic from [Google](http://google.com/ &quot;Google&quot;)
+than from [Yahoo](http://search.yahoo.com/ &quot;Yahoo Search&quot;) or
+[MSN](http://search.msn.com/ &quot;MSN Search&quot;).
+</code></pre>
+
+<p>The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.</p>
+
+<p>With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.</p>
+
+<h3 id="em">Emphasis</h3>
+
+<p>Markdown treats asterisks (<code>*</code>) and underscores (<code>_</code>) as indicators of
+emphasis. Text wrapped with one <code>*</code> or <code>_</code> will be wrapped with an
+HTML <code>&lt;em&gt;</code> tag; double <code>*</code>'s or <code>_</code>'s will be wrapped with an HTML
+<code>&lt;strong&gt;</code> tag. E.g., this input:</p>
+
+<pre><code>*single asterisks*
+
+_single underscores_
+
+**double asterisks**
+
+__double underscores__
+</code></pre>
+
+<p>will produce:</p>
+
+<pre><code>&lt;em&gt;single asterisks&lt;/em&gt;
+
+&lt;em&gt;single underscores&lt;/em&gt;
+
+&lt;strong&gt;double asterisks&lt;/strong&gt;
+
+&lt;strong&gt;double underscores&lt;/strong&gt;
+</code></pre>
+
+<p>You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.</p>
+
+<p>Emphasis can be used in the middle of a word:</p>
+
+<pre><code>un*fucking*believable
+</code></pre>
+
+<p>But if you surround an <code>*</code> or <code>_</code> with spaces, it'll be treated as a
+literal asterisk or underscore.</p>
+
+<p>To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:</p>
+
+<pre><code>\*this text is surrounded by literal asterisks\*
+</code></pre>
+
+<h3 id="code">Code</h3>
+
+<p>To indicate a span of code, wrap it with backtick quotes (<code>`</code>).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:</p>
+
+<pre><code>Use the `printf()` function.
+</code></pre>
+
+<p>will produce:</p>
+
+<pre><code>&lt;p&gt;Use the &lt;code&gt;printf()&lt;/code&gt; function.&lt;/p&gt;
+</code></pre>
+
+<p>To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:</p>
+
+<pre><code>``There is a literal backtick (`) here.``
+</code></pre>
+
+<p>which will produce this:</p>
+
+<pre><code>&lt;p&gt;&lt;code&gt;There is a literal backtick (`) here.&lt;/code&gt;&lt;/p&gt;
+</code></pre>
+
+<p>The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:</p>
+
+<pre><code>A single backtick in a code span: `` ` ``
+
+A backtick-delimited string in a code span: `` `foo` ``
+</code></pre>
+
+<p>will produce:</p>
+
+<pre><code>&lt;p&gt;A single backtick in a code span: &lt;code&gt;`&lt;/code&gt;&lt;/p&gt;
+
+&lt;p&gt;A backtick-delimited string in a code span: &lt;code&gt;`foo`&lt;/code&gt;&lt;/p&gt;
+</code></pre>
+
+<p>With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:</p>
+
+<pre><code>Please don't use any `&lt;blink&gt;` tags.
+</code></pre>
+
+<p>into:</p>
+
+<pre><code>&lt;p&gt;Please don't use any &lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
+</code></pre>
+
+<p>You can write this:</p>
+
+<pre><code>`&amp;#8212;` is the decimal-encoded equivalent of `&amp;mdash;`.
+</code></pre>
+
+<p>to produce:</p>
+
+<pre><code>&lt;p&gt;&lt;code&gt;&amp;amp;#8212;&lt;/code&gt; is the decimal-encoded
+equivalent of &lt;code&gt;&amp;amp;mdash;&lt;/code&gt;.&lt;/p&gt;
+</code></pre>
+
+<h3 id="img">Images</h3>
+
+<p>Admittedly, it's fairly difficult to devise a &quot;natural&quot; syntax for
+placing images into a plain text document format.</p>
+
+<p>Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: <em>inline</em> and <em>reference</em>.</p>
+
+<p>Inline image syntax looks like this:</p>
+
+<pre><code>![Alt text](/path/to/img.jpg)
+
+![Alt text](/path/to/img.jpg &quot;Optional title&quot;)
+</code></pre>
+
+<p>That is:</p>
+
+<ul>
+<li>An exclamation mark: <code>!</code>;</li>
+<li>followed by a set of square brackets, containing the <code>alt</code>
+attribute text for the image;</li>
+<li>followed by a set of parentheses, containing the URL or path to
+the image, and an optional <code>title</code> attribute enclosed in double
+or single quotes.</li>
+</ul>
+
+<p>Reference-style image syntax looks like this:</p>
+
+<pre><code>![Alt text][id]
+</code></pre>
+
+<p>Where &quot;id&quot; is the name of a defined image reference. Image references
+are defined using syntax identical to link references:</p>
+
+<pre><code>[id]: url/to/image  &quot;Optional title attribute&quot;
+</code></pre>
+
+<p>As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML <code>&lt;img&gt;</code> tags.</p>
+
+<hr>
+
+<h2 id="misc">Miscellaneous</h2>
+
+<h3 id="autolink">Automatic Links</h3>
+
+<p>Markdown supports a shortcut style for creating &quot;automatic&quot; links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:</p>
+
+<pre><code>&lt;http://example.com/&gt;
+</code></pre>
+
+<p>Markdown will turn this into:</p>
+
+<pre><code>&lt;a href=&quot;http://example.com/&quot;&gt;http://example.com/&lt;/a&gt;
+</code></pre>
+
+<p>Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:</p>
+
+<pre><code>&lt;address@example.com&gt;
+</code></pre>
+
+<p>into something like this:</p>
+
+<pre><code>&lt;a href=&quot;&amp;#x6D;&amp;#x61;i&amp;#x6C;&amp;#x74;&amp;#x6F;:&amp;#x61;&amp;#x64;&amp;#x64;&amp;#x72;&amp;#x65;
+&amp;#115;&amp;#115;&amp;#64;&amp;#101;&amp;#120;&amp;#x61;&amp;#109;&amp;#x70;&amp;#x6C;e&amp;#x2E;&amp;#99;&amp;#111;
+&amp;#109;&quot;&gt;&amp;#x61;&amp;#x64;&amp;#x64;&amp;#x72;&amp;#x65;&amp;#115;&amp;#115;&amp;#64;&amp;#101;&amp;#120;&amp;#x61;
+&amp;#109;&amp;#x70;&amp;#x6C;e&amp;#x2E;&amp;#99;&amp;#111;&amp;#109;&lt;/a&gt;
+</code></pre>
+
+<p>which will render in a browser as a clickable link to &quot;address@example.com&quot;.</p>
+
+<p>(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)</p>
+
+<h3 id="backslash">Backslash Escapes</h3>
+
+<p>Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML <code>&lt;em&gt;</code> tag), you can backslashes
+before the asterisks, like this:</p>
+
+<pre><code>\*literal asterisks\*
+</code></pre>
+
+<p>Markdown provides backslash escapes for the following characters:</p>
+
+<pre><code>\   backslash
+`   backtick
+*   asterisk
+_   underscore
+{}  curly braces
+[]  square brackets
+()  parentheses
+#   hash mark
++   plus sign
+-   minus sign (hyphen)
+.   dot
+!   exclamation mark
+</code></pre>

+<h2 id="overview">Overview</h2>
+
+<h3 id="philosophy">Philosophy</h3>
+
+Markdown is intended to be as easy-to-read and easy-to-write as is feasible.
+
+Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including [Setext] [1], [atx] [2], [Textile] [3], [reStructuredText] [4],
+[Grutatext] [5], and [EtText] [6] -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.
+
+  [1]: http://docutils.sourceforge.net/mirror/setext.html
+  [2]: http://www.aaronsw.com/2002/atx/
+  [3]: http://textism.com/tools/textile/
+  [4]: http://docutils.sourceforge.net/rst.html
+  [5]: http://www.triptico.com/software/grutatxt.html
+  [6]: http://ettext.taint.org/doc/
+
+To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like \*emphasis\*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.
+
+
+
+<h3 id="html">Inline HTML</h3>
+
+Markdown's syntax is intended for one purpose: to be used as a
+format for *writing* for the web.
+
+Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is *not* to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a *publishing* format; Markdown is a *writing*
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.
+
+For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.
+
+The only restrictions are that block-level HTML elements -- e.g. `<div>`,
+`<table>`, `<pre>`, `<p>`, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) `<p>` tags around HTML block-level tags.
+
+For example, to add an HTML table to a Markdown article:
+
+    This is a regular paragraph.
+
+    <table>
+        <tr>
+            <td>Foo</td>
+        </tr>
+    </table>
+
+    This is another regular paragraph.
+
+Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style `*emphasis*` inside an
+HTML block.
+
+Span-level HTML tags -- e.g. `<span>`, `<cite>`, or `<del>` -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML `<a>` or `<img>` tags instead of Markdown's
+link or image syntax, go right ahead.
+
+Unlike block-level HTML tags, Markdown syntax *is* processed within
+span-level tags.
+
+
+<h3 id="autoescape">Automatic Escaping for Special Characters</h3>
+
+In HTML, there are two characters that demand special treatment: `<`
+and `&`. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. `&lt;`, and
+`&amp;`.
+
+Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&T', you need to write '`AT&amp;T`'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+you need to encode the URL as:
+
+    http://images.google.com/images?num=30&amp;q=larry+bird
+
+in your anchor tag `href` attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.
+
+Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into `&amp;`.
+
+So, if you want to include a copyright symbol in your article, you can write:
+
+    &copy;
+
+and Markdown will leave it alone. But if you write:
+
+    AT&T
+
+Markdown will translate it to:
+
+    AT&amp;T
+
+Similarly, because Markdown supports [inline HTML](#html), if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:
+
+    4 < 5
+
+Markdown will translate it to:
+
+    4 &lt; 5
+
+However, inside Markdown code spans and blocks, angle brackets and
+ampersands are *always* encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single `<`
+and `&` in your example code needs to be escaped.)
+
+
+* * *
+
+
+<h2 id="block">Block Elements</h2>
+
+
+<h3 id="p">Paragraphs and Line Breaks</h3>
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.
+
+The implication of the "one or more consecutive lines of text" rule is
+that Markdown supports "hard-wrapped" text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's "Convert Line Breaks" option) which translate every line break
+character in a paragraph into a `<br />` tag.
+
+When you *do* want to insert a `<br />` break tag using Markdown, you
+end a line with two or more spaces, then type return.
+
+Yes, this takes a tad more effort to create a `<br />`, but a simplistic
+"every line break is a `<br />`" rule wouldn't work for Markdown.
+Markdown's email-style [blockquoting][bq] and multi-paragraph [list items][l]
+work best -- and look better -- when you format them with hard breaks.
+
+  [bq]: #blockquote
+  [l]:  #list
+
+
+
+<h3 id="header">Headers</h3>
+
+Markdown supports two styles of headers, [Setext] [1] and [atx] [2].
+
+Setext-style headers are "underlined" using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:
+
+    This is an H1
+    =============
+
+    This is an H2
+    -------------
+
+Any number of underlining `=`'s or `-`'s will work.
+
+Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:
+
+    # This is an H1
+
+    ## This is an H2
+
+    ###### This is an H6
+
+Optionally, you may "close" atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :
+
+    # This is an H1 #
+
+    ## This is an H2 ##
+
+    ### This is an H3 ######
+
+
+<h3 id="blockquote">Blockquotes</h3>
+
+Markdown uses email-style `>` characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a `>` before every line:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+    > 
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    > id sem consectetuer libero luctus adipiscing.
+
+Markdown allows you to be lazy and only put the `>` before the first
+line of a hard-wrapped paragraph:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    id sem consectetuer libero luctus adipiscing.
+
+Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of `>`:
+
+    > This is the first level of quoting.
+    >
+    > > This is nested blockquote.
+    >
+    > Back to the first level.
+
+Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:
+
+	> ## This is a header.
+	> 
+	> 1.   This is the first list item.
+	> 2.   This is the second list item.
+	> 
+	> Here's some example code:
+	> 
+	>     return shell_exec("echo $input | $markdown_script");
+
+Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.
+
+
+<h3 id="list">Lists</h3>
+
+Markdown supports ordered (numbered) and unordered (bulleted) lists.
+
+Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:
+
+    *   Red
+    *   Green
+    *   Blue
+
+is equivalent to:
+
+    +   Red
+    +   Green
+    +   Blue
+
+and:
+
+    -   Red
+    -   Green
+    -   Blue
+
+Ordered lists use numbers followed by periods:
+
+    1.  Bird
+    2.  McHale
+    3.  Parish
+
+It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:
+
+    <ol>
+    <li>Bird</li>
+    <li>McHale</li>
+    <li>Parish</li>
+    </ol>
+
+If you instead wrote the list in Markdown like this:
+
+    1.  Bird
+    1.  McHale
+    1.  Parish
+
+or even:
+
+    3. Bird
+    1. McHale
+    8. Parish
+
+you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.
+
+If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.
+
+List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.
+
+To make lists look nice, you can wrap items with hanging indents:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+        Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+        viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+        Suspendisse id sem consectetuer libero luctus adipiscing.
+
+But if you want to be lazy, you don't have to:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+If list items are separated by blank lines, Markdown will wrap the
+items in `<p>` tags in the HTML output. For example, this input:
+
+    *   Bird
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li>Bird</li>
+    <li>Magic</li>
+    </ul>
+
+But this:
+
+    *   Bird
+
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li><p>Bird</p></li>
+    <li><p>Magic</p></li>
+    </ul>
+
+List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be intended by either 4 spaces
+or one tab:
+
+    1.  This is a list item with two paragraphs. Lorem ipsum dolor
+        sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+        mi posuere lectus.
+
+        Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+        vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+        sit amet velit.
+
+    2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+
+It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:
+
+    *   This is a list item with two paragraphs.
+
+        This is the second paragraph in the list item. You're
+    only required to indent the first line. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit.
+
+    *   Another item in the same list.
+
+To put a blockquote within a list item, the blockquote's `>`
+delimiters need to be indented:
+
+    *   A list item with a blockquote:
+
+        > This is a blockquote
+        > inside a list item.
+
+To put a code block within a list item, the code block needs
+to be indented *twice* -- 8 spaces or two tabs:
+
+    *   A list item with a code block:
+
+            <code goes here>
+
+
+It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:
+
+    1986. What a great season.
+
+In other words, a *number-period-space* sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:
+
+    1986\. What a great season.
+
+
+
+<h3 id="precode">Code Blocks</h3>
+
+Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both `<pre>` and `<code>` tags.
+
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+
+    This is a normal paragraph:
+
+        This is a code block.
+
+Markdown will generate:
+
+    <p>This is a normal paragraph:</p>
+
+    <pre><code>This is a code block.
+    </code></pre>
+
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+
+will turn into:
+
+    <p>Here is an example of AppleScript:</p>
+
+    <pre><code>tell application "Foo"
+        beep
+    end tell
+    </code></pre>
+
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+
+        <div class="footer">
+            &copy; 2004 Foo Corporation
+        </div>
+
+will turn into:
+
+    <pre><code>&lt;div class="footer"&gt;
+        &amp;copy; 2004 Foo Corporation
+    &lt;/div&gt;
+    </code></pre>
+
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+
+
+
+<h3 id="hr">Horizontal Rules</h3>
+
+You can produce a horizontal rule tag (`<hr />`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+
+    * * *
+
+    ***
+
+    *****
+	
+    - - -
+

+
+<h2 id="span">Span Elements</h2>
+
+<h3 id="link">Links</h3>
+
+Markdown supports two style of links: *inline* and *reference*.
+
+In both styles, the link text is delimited by [square brackets].
+
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+
+Will produce:
+
+    <p>This is <a href="http://example.com/" title="Title">
+    an example</a> inline link.</p>
+
+    <p><a href="http://example.net/">This link</a> has no
+    title attribute.</p>
+
+If you're referring to a local resource on the same server, you can
+use relative paths:
+
+    See my [About](/about/) page for details.
+
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+
+    This is [an example][id] reference-style link.
+
+You can optionally use a space to separate the sets of brackets:
+
+    This is [an example] [id] reference-style link.
+
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+
+    [id]: http://example.com/  "Optional Title Here"
+
+That is:
+
+*   Square brackets containing the link identifier (optionally
+    indented from the left margin using up to three spaces);
+*   followed by a colon;
+*   followed by one or more spaces (or tabs);
+*   followed by the URL for the link;
+*   optionally followed by a title attribute for the link, enclosed
+    in double or single quotes.
+
+The link URL may, optionally, be surrounded by angle brackets:
+
+    [id]: <http://example.com/>  "Optional Title Here"
+
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+
+Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are *not* case sensitive. E.g. these two links:
+
+	[link text][a]
+	[link text][A]
+
+are equivalent.
+
+The *implicit link name* shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+"Google" to the google.com web site, you could simply write:
+
+	[Google][]
+
+And then define the link:
+
+	[Google]: http://google.com/
+
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+
+	Visit [Daring Fireball][] for more information.
+
+And then define the link:
+	
+	[Daring Fireball]: http://daringfireball.net/
+
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+
+Here's an example of reference links in action:
+
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+
+Using the implicit link name shortcut, you could instead write:
+
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+
+Both of the above examples will produce the following HTML output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from
+    <a href="http://search.yahoo.com/" title="Yahoo Search">Yahoo</a>
+    or <a href="http://search.msn.com/" title="MSN Search">MSN</a>.</p>
+
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+
+    I get 10 times more traffic from [Google](http://google.com/ "Google")
+    than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+
+
+<h3 id="em">Emphasis</h3>
+
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `<em>` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`<strong>` tag. E.g., this input:
+
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+
+will produce:
+
+    <em>single asterisks</em>
+
+    <em>single underscores</em>
+
+    <strong>double asterisks</strong>
+
+    <strong>double underscores</strong>
+
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+
+Emphasis can be used in the middle of a word:
+
+    un*fucking*believable
+
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+
+    \*this text is surrounded by literal asterisks\*
+
+
+
+<h3 id="code">Code</h3>
+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+
+    Use the `printf()` function.
+
+will produce:
+
+    <p>Use the <code>printf()</code> function.</p>
+
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+
+    ``There is a literal backtick (`) here.``
+
+which will produce this:
+
+    <p><code>There is a literal backtick (`) here.</code></p>
+
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+
+will produce:
+
+	<p>A single backtick in a code span: <code>`</code></p>
+	
+	<p>A backtick-delimited string in a code span: <code>`foo`</code></p>
+
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+
+    Please don't use any `<blink>` tags.
+
+into:
+
+    <p>Please don't use any <code>&lt;blink&gt;</code> tags.</p>
+
+You can write this:
+
+    `&#8212;` is the decimal-encoded equivalent of `&mdash;`.
+
+to produce:
+
+    <p><code>&amp;#8212;</code> is the decimal-encoded
+    equivalent of <code>&amp;mdash;</code>.</p>
+
+
+
+<h3 id="img">Images</h3>
+
+Admittedly, it's fairly difficult to devise a "natural" syntax for
+placing images into a plain text document format.
+
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: *inline* and *reference*.
+
+Inline image syntax looks like this:
+
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg "Optional title")
+
+That is:
+
+*   An exclamation mark: `!`;
+*   followed by a set of square brackets, containing the `alt`
+    attribute text for the image;
+*   followed by a set of parentheses, containing the URL or path to
+    the image, and an optional `title` attribute enclosed in double
+    or single quotes.
+
+Reference-style image syntax looks like this:
+
+    ![Alt text][id]
+
+Where "id" is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+
+    [id]: url/to/image  "Optional title attribute"
+
+As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML `<img>` tags.
+
+
+* * *
+
+
+<h2 id="misc">Miscellaneous</h2>
+
+<h3 id="autolink">Automatic Links</h3>
+
+Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:
+
+    <http://example.com/>
+    
+Markdown will turn this into:
+
+    <a href="http://example.com/">http://example.com/</a>
+
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+
+    <address@example.com>
+
+into something like this:
+
+    <a href="&#x6D;&#x61;i&#x6C;&#x74;&#x6F;:&#x61;&#x64;&#x64;&#x72;&#x65;
+    &#115;&#115;&#64;&#101;&#120;&#x61;&#109;&#x70;&#x6C;e&#x2E;&#99;&#111;
+    &#109;">&#x61;&#x64;&#x64;&#x72;&#x65;&#115;&#115;&#64;&#101;&#120;&#x61;
+    &#109;&#x70;&#x6C;e&#x2E;&#99;&#111;&#109;</a>
+
+which will render in a browser as a clickable link to "address@example.com".
+
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+
+
+
+<h3 id="backslash">Backslash Escapes</h3>
+
+Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML `<em>` tag), you can backslashes
+before the asterisks, like this:
+
+    \*literal asterisks\*
+
+Markdown provides backslash escapes for the following characters:
+
+    \   backslash
+    `   backtick
+    *   asterisk
+    _   underscore
+    {}  curly braces
+    []  square brackets
+    ()  parentheses
+    #   hash mark
+	+	plus sign
+	-	minus sign (hyphen)
+    .   dot
+    !   exclamation mark
+
