   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 copy to '~/.zsh/_git', and
  15 # then add the following to your ~/.zshrc file:
  16 #
  17 #  fpath=(~/.zsh $fpath)
