+# git-extras
+
+This plugin provides completion definitions for some of the commands defined by [git-extras](http://github.com/tj/git-extras).
+
+##  Setup notes
+
+The completions work by augmenting the `_git` completion provided by `zsh`. This only works with the `zsh`-provided `_git`, not the `_git` provided by `git` itself. If you have both `zsh` and `git` installed, you need to make sure that the `zsh`-provided `_git` takes precedence.
+
+### OS X Homebrew Setup
+
+On OS X with Homebrew, you need to install `git` with `brew install git --without-completions`. Otherwise, `git`'s `_git` will take precedence, and you won't see the completions for `git-extras` commands.

 #  Completion script for git-extras (http://github.com/tj/git-extras).

+#  This depends on and reueses some of the internals of the _git completion
+#  function that ships with zsh itself. It will not work with the _git that ships
+#  with git.
