-The Git stuff
-=============
-
-General commit rules
---------------------
-
-1. All changes introduced by the commit (diff lines) must be related to the
-   subject of the commit.
-
-   If you change some other unrelated to the subject parts of the file, because
-   your editor reformatted automatically the code or whatever different reason,
-   this should be excluded from the commit.
-
-   *Tip:* Never commit everything as is using ``git commit -a``, but review
-   carefully your changes with ``git add -p``.
-
-2. Changes should not introduce any trailing whitespace.
-
-   Always check your changes for whitespace errors using ``git diff --check``
-   or add following ``pre-commit`` hook:
-
-   .. code-block:: sh
-
-      #!/bin/sh
-      git diff --check --cached || exit $?
-
-   No sane programming or markup language cares about trailing whitespace, so
-   tailing whitespace is just a noise you should not introduce to the
-   repository.
-
-3. Describe your commit well following the 50/72 rule on commit messages:
-
-   Start with the commit subject as single line maximum of 50 characters,
-   without trailing period, briefly describing the change.
-
-   Optionally put the detailed description as a blocks of text wrapped to 72
-   characters, separated by single blank line from the other parts (including
-   the subject).
