+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.
+
+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 following theme codes for example:
+
+    function _virtualenv_prompt_info {
+            [[ -n $(whence virtualenv_prompt_info) ]] && virtualenv_prompt_info
+    }
+
+    function _nodeenv_prompt_info {
+            [[ -n $(whence nodeenv_prompt_info) ]] && nodeenv_prompt_info
+    }
+
+    ZSH_THEME_GIT_PROMPT_PREFIX=" %{$fg[green]%}"
+    ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%}"
+    ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[red]%}!"
+    ZSH_THEME_GIT_PROMPT_CLEAN=""
+
+    function prompt_char {
+                if [ $UID -eq 0 ]; then echo "%{$fg[red]%}#%{$reset_color%}"; else echo $; fi
+    }
+
+    PROMPT='%(?, ,%{$fg[red]%}FAIL%{$reset_color%}
+    )
+    $(_nodeenv_prompt_info)$(_virtualenv_prompt_info)%{$fg[magenta]%}%n%{$reset_color%}@%{$fg[yellow]%}%m%{$reset_color%}: %{$fg_bold[blue]%}%~%{$reset_color%}$(git_prompt_info)
+    %_ $(prompt_char) '
+
+    RPROMPT='%{$fg[green]%}[%*]%{$reset_color%}'
