It's a tiny and beautiful theme for Oh-My-Zsh without something superfluous, it'll only show * if the git index is not empty and ≠ if current branch needs to be rebased on a default branch. The default branch is master by default, but you can override it for particular repos by creating .git/safe/default_branch file with the branch name in it:

mkdir .git/safe/
touch .git/safe/default_branch
echo develop > .git/safe/default_branch

You can find more info about .git/safe here.

• First of all you need Zsh shell and Oh-My-Zsh framework to be installed. Then get file with theme:

wget -P $ZSH/themes https://raw.githubusercontent.com/ARtoriouSs/chaotic-beef-zsh-theme/master/chaotic-beef.zsh-theme

• After that change the following line in your .zshrc file in $HOME directory:

ZSH_THEME="chaotic-beef"

• Don't forget to relogin
