title: Do I need a "Users" controller when using Devise in Rails
body: <p>I am a Rails newbie. I am working on a small Rails4 project trying to improve my skills.
  I am loosely following <a href="http://www.railstutorial.org/book">M.Hartl's tutorial</a>.</p>
  
  <p>As per the tutorial a custom user authentication is built.
  However I would like to use Devise for User authentication.
  Do I still need to have a Users controller as in the tutorial?
  In which cases should I use/not use a Users controller when already using Devise?</p>
  
  <p>Concerning the tutorial, do I just skip the controller generating part or do I have to map the actions to Devise?</p>
