title: How to integrate Grunt with Rails Asset Pipeline
body: <p>The question is: how do you integrate Rails with Grunt?</p>
  
  <p>Just a quick brainstorm and I figured out that I <strong>need</strong>:</p>
  
  <ul>
  <li>PhanomJS</li>
  <li>Jasmine</li>
  <li>JSHint / JSLint</li>
  </ul>
  
  <p>I <strong>do not need</strong> or I don't know if I need (it's up to Rails) :)</p>
  
  <ul>
  <li>minification</li>
  <li>uglification (obfuscation)</li>
  <li>concatenation</li>
  </ul>
  
  <p>How do I integrate it with an existing Rails app? What steps shoud I take in order to make it work? Where should Grunt files / config reside?
  And the final question: does it intefere with Rails assets?</p>
