title: Learning Ruby on rails
body: <p>I need a good guide about learning Ruby on Rails. </p>
  
  <p>I found <a href="http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#top" rel="nofollow">this</a>, and I want some opinions on it. Is it good or outdated? It dates back to 2010, so I don't think is that old.</p>
  
  <p>Any suggestions? Thanks! </p>
