+## Build cephadm using the Makefile
+
+A Makefile is provided with the purpose of automating the steps described before.
+It provides an helper function and can be used to build the srpm, as well as obtaining
+additional information on the current build.
+The act of running the 'cbs build' command is not automated on the Makefile since it's out
+of scope: feel free to refer to the last step of the previous section to run the cbs build
+after the Makefile execution ends.
+
+### Executing the Makefile without parameters
+
+If no parameters are provided, the Makefile computes the branch name, the version
+and the release from the current spec file.
+The Release field is increased by 1 but the version remains the same: this is because
+we're building the package against a newer hash instead of bumping the cephadm version
+according to the provided tags (the ceph-ansible approach).
+
+If you want to produce a new srpm for an existing cephadm version, just run:
+
+```
+make
+```
+
+and you will see an output like this:
+
+```
+[fmount@buildbot cephadm]$ make
+sed SPECS/cephadm.spec.in \
+  -e "s/89ceb19fd8609fd4c99d10dd63f42e6786e37c86/dcf77bd9ff89dfef682c4a2dda05ac5c8651dbe5/" \
+  -e 's/@VERSION@/15.2.10/' \
+  -e 's/@RELEASE@/2/' \

+```
+
+In addition, a cephadm.spec file is generated from the input `SPECS/cephadm.spec.in` and it can be
+found under the SPECS directory.
+
+At the end of this process, as described in the previous section, you can run the cbs build:
+
+```
+    $ cbs build [--scratch] storage8-ceph-octopus-el8 cephadm-15.2.10-2.el8.src.rpm
+```
+
+
+### Executing the Makefile overriding some input parameters
+
+If you want to bump to a newer released version, the hash computation remains unchanged,
+but you might want to patch the spec input file properly.
+For this reason a few parameters, exposed via the `cephadm.spec.in` file can be overrided:
+
+* RELEASE
+* DIST = el8 by default
+* VERSION
+
+For instance, assuming we have the following data in the current spec:
+
+[fmount@buildbot cephadm]$ cat SPECS/cephadm.spec | grep -iE "(Release|Version)"
+Version: 15.2.10
+Release: 2%{?dist}
+
+you can patch (and bump to a newer NVR) the current (existing) spec file by running:
+
+```
+DIST=el8 RELEASE=1 VERSION=15.2.11 make
+```
+
+Then, running the regular cbs build command a new cephadm rpm can be built:
+
+```
+    $ cbs build [--scratch] storage8-ceph-octopus-el8 cephadm-15.2.10-2.el8.src.rpm
+```
