+oh-my-zsh::plugin::nodeenv-prompt
+====================================
+
+This is a plugin derived from
+[virtualenv prompt](https://github.com/tonyseek/oh-my-zsh-virtualenv-prompt).
+It support to customize the
+[nodeenv](https://github.com/ekalinin/nodeenv)
+prompt in oh-my-zsh themes.
+
+Installation
+------------
+
+You can install this plugin from shell:
+
+    repo="git://github.com/chenhouwu/oh-my-zsh-nodeenv-prompt.git"
+    target="$HOME/.oh-my-zsh/custom/plugins/nodeenv-prompt"
+
+    git clone $repo $target
+
+
+Customize Theme
+---------------
+
+There are two constant strings which could be overrided in your custom theme.
+
+- `ZSH_THEME_NODEENV_PROMPT_PREFIX`
+- `ZSH_THEME_NODEENV_PROMPT_SUFFIX`
+
+And the function `nodeenv_prompt_info` could be used in the prompt of your
+theme.
+
+Example
+-------
+
+See the [oh-my-zsh::theme::seeker](https://github.com/tonyseek/oh-my-zsh-seeker-theme).
