 The primary job of this plugin is to provide `rbenv_prompt_info` which can be added to your theme to include Ruby
 version and gemset information into your prompt.
 
+Additionally, this plugin provides completion for the `rbenv` command. See also <https://github.com/rbenv/rbenv/#shell-completions>.

 Some functionality of this plugin will not work unless you also have the rbenv plugin *gemset* installed.
