+# nodenv plugin
+
+The primary job of this plugin is to provide `nodenv_prompt_info` which can be added to your theme to include Node
+version information into your prompt.
+
+To use it, add `nodenv` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... nodenv)
+```
+
+## Functions
+
+* `nodenv_prompt_info`: displays the Node version in use by nodenv; or the global Node
+  version, if nodenv wasn't found. You can use this function in your prompt by adding
+  `$(nodenv_prompt_info)` to PROMPT or RPROMPT:
+
+  ```zsh
+  RPROMPT='$(nodenv_prompt_info)'
+  ```
