title: Install package modules for Linter package in Atom
body: <p>I'm using <a href="https://atom.io/" rel="nofollow">the Atom text editor</a>, and have installed the the '<a href="https://atom.io/packages/linter" rel="nofollow">Linter</a>' package so I can get realtime debugging/error reports when editing.</p>
  
  <p>Atom has an UI for auto-installing packages - one-click installs, so I have no idea how to do it manually. </p>
  
  <p>I'm very new to Git, and coding in general, so the installation instructions in the documentation for this package are not very helpful (for me).</p>
  
  <p>Basically, I'm trying to install/run/get PHP validation going when I'm using Atom text editor. How can I do this?</p>
