   7 # You need git's bash completion script installed somewhere, by default it
   8 # would be the location bash-completion uses.
   9 #
  10 # If your script is somewhere else, you can configure it on your ~/.zshrc:
  11 #
  12 #  zstyle ':completion:*:*:git:*' script ~/.git-completion.zsh
  13 #
  14 # The recommended way to install this script is to make a copy of it in
  15 # ~/.zsh/ directory as ~/.zsh/git-completion.zsh and then add the following
  16 # to your ~/.zshrc file:
  17 #
  18 #  fpath=(~/.zsh $fpath)
