+# GitHub CLI plugin
+
+This plugin adds completion for the [GitHub CLI](https://cli.github.com/).
+
+To use it, add `gh` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... gh)
+```
+
+This plugin does not add any aliases.
+
+## Cache
+
+This plugin caches the completion script and is automatically updated when the
+plugin is loaded, which is usually when you start up a new terminal emulator.
+
+The cache is stored at:
+
+- `$ZSH/plugins/gh/_gh` completions script
+
+- `$ZSH_CACHE_DIR/gh_version` version of GitHub CLI, used to invalidate
+  the cache.
