Commandline git branch description (NOT MINE, just sharing). Paste at the end of your ~/.bashrc or ~/.profile or ~/.bash_profile (check out which one you have first). After pasting and saving it, type "source ~/.bashrc" (or .profile or .bash_profile) and get inside any repo to check if it worked =)
