+Provides utility functions for [Node.js][1], loads the Node Version Manager, and
+enables [npm][2] completion.
+
+nvm
+---
+
+[nvm][5] allows for managing multiple, isolated Node.js installations in the
+home directory.
 
 Functions
 ---------
 
   - `node-doc` opens the Node.js online [API documentation][3] in the default
     browser.
+  - `node-info` exposes information about the Node.js environment via the
+    `$node_info` associative array.
+
+Theming
+-------
+
+To display the version number of the current Node.js version, define the
+following style inside the `prompt_name_setup` function.
+
+    # %v - Node.js version.
+    zstyle ':prezto:module:node:info:version' format 'version:%v'
+
+Then add `$node_info[version]` to either `$PROMPT` or `$RPROMPT` and call
+`node-info` in `prompt_name_preexec` hook function.
