The first step in producing a documentation manual is to clearly understand what you exactly need to document and why you need to do so. The obvious answer to this question would be to describe the basic ideas behind an implementation so it can be useful once published. It is important that you find out the reasons you need to do what you are doing and, also, those helping you to retain the motivation to keep doing it in the future. Otherwise, without such foundations, you'll surely end up leaving the effort soon enough to make a lost cause from your initial work. Before The CentOS Artwork Repository File System documentation manual exist, there was an emerging need to understand what each directory inside the growing directory layout was for, how they could be used and how they could be connected one another. At that moment, the directory layout was very unstable and explaining the whole idea behind it was not possible, there were too many changing concepts floating around which needed to be considered in the same changing way. So, to understand what was happening, the The CentOS Artwork Repository File System documentation manual was created. The The CentOS Artwork Repository File System manual was conceived based on the idea of individually documenting each directory inside the repository and, later, by considering all directory documentations together, it would be (hypothetically) possible to correct the whole idea through an improvement cycle that would consolidate the final idea we try to implement. Other documentation manuals can be based on reasons different from those described above, however, no matter what those reasons be, it will be helpful to make yourself a clean idea about what you are going to document exactly before putting your hands on it.
