# Installation  

_\*For simplicity, let's use **[VIM_ROOT]** which will mean ~/.vim (\*nix) or ~/vimfiles (Windows)_

The NERD Commenter requires Vim 7 or higher is comprised of 2 files:  

    plugin/NERD_commenter.vim  
    doc/NERD_commenter.txt 

### Classic Install

1. Extract the plugin files into your **[VIM_ROOT]**/plugin and **[VIM_ROOT]**/doc folders respectively.
2. Finish the install by updating your help files.  Run:

<pre><code>:helptags [VIM_ROOT]/doc</code></pre>

See **|add-local-help|** for more details. 

### Pathogen Install
1. Navigate to your **[VIM_ROOT]/bundle** directory in your local Vim setup
2. `git clone https://github.com/scrooloose/nerdcommenter.git`

### Vundle Install
1. Add `Plugin 'scrooloose/nerdcommenter'` to your .vimrc file.
2. Run `:BundleInstall`

### Post Install  
After the **'Classic'** or **'Pathogen'** install, make sure that you have filetype plugins enabled, as the script makes use of 
**|'commentstring'|** where possible (which is usually set in a filetype plugin). 
See **|filetype-plugin-on|** for details, but basically, stick this in your vimrc:

    filetype plugin on
