## 3. Installation
### Selecting Particular Linters
To install this plugin, you should use one of the following methods.
For Windows users, replace usage of the Unix `~/.vim` directory with
`%USERPROFILE%\_vim`, or another directory if you have configured
Vim differently. On Windows, your `~/.vimrc` file will be similarly
stored in `%USERPROFILE%\_vimrc`.
<a name="installation-with-pathogen"></a>
### 3.1. Installation with Pathogen
To install this module with [Pathogen](https://github.com/tpope/vim-pathogen),
you should clone this repository to your bundle directory, and ensure
you have the line `execute pathogen#infect()` in your `~/.vimrc` file.
You can run the following commands in your terminal to do so:
```bash
cd ~/.vim/bundle
git clone https://github.com/w0rp/ale.git
```

```vim
Plugin 'w0rp/ale'
```
See the Vundle documentation for more information.
<a name="manual-installation"></a>
### 3.3. Manual Installation
For installation without a package manager, you can clone this git repository
into a bundle directory as with pathogen, and add the repository to your
runtime path yourself. First clone the repository.
```bash
cd ~/.vim/bundle
git clone https://github.com/w0rp/ale.git
```
Then, modify your `~/.vimrc` file to add this plugin to your runtime path.
```vim
set nocompatible
filetype off
let &runtimepath.=',~/.vim/bundle/ale'
filetype plugin on
```
You can add the following line to generate documentation tags automatically,
if you don't have something similar already, so you can use the `:help` command
to consult ALE's online documentation:
```vim
silent! helptags ALL
```
Because the author of this plugin is a weird nerd, this is his preferred
installation method.
