+# rbenv plugin
+
+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.
+
+Some functionality of this plugin will not work unless you also have the rbenv plugin *gemset* installed.
+https://github.com/jf/rbenv-gemset
+
+To use it, add `rbenv` to the plugins array in your zshrc file:
+```zsh
+plugins=(... rbenv)
+```
+
