• Add git-status-prompt in your PATH ln -s /path/to/git-utils/git-status-prompt ~/bin/git-status-prompt
• Add $(git-status-prompt) to the PS1 variable in your ~/.bashrc.

For instance, mine is

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]$(git-status-prompt)\$ '

Quick install script:

sed -i "s@\(\\\\\]\)\(\\\\\$ '\)@\1\$($(pwd)/git-status-prompt)\2@" ~/.bashrc
