+bash/zsh completion
+-------------------
+
+It's a bit hard to type ``git rebase --interactive --preserve-merges
+HEAD~5`` manually even for those who are happy to use command-line,
+and this is where shell completion is of great help. Bash/zsh come
+with programmable completion, often automatically preinstalled and
+enabled, so if you have bash/zsh and git installed, chances are you
+are already done - just go and use it at the command-line.
+
+If you don't have necessary bits preinstalled, install and enable
+bash_completion package. If you want to upgrade your git completion to
+the latest and greatest download necessary file from `git contrib
+<https://git.kernel.org/cgit/git/git.git/tree/contrib/completion>`_.
+
+Git-for-windows comes with git-bash, bash completion is installed and
+enabled.
