title: Ruby on Rails API Tutorial
body: <p>I've never worked with or written an API before. To help me learn, I want to write a Facebook API library RubyGem. </p>
  
  <p>I'm thinking I should start with learning how to write a simple API with RoR. </p>
  
  <p>Do you know of any good resources or tutorials that will help me learn how to write an API with Ruby?</p>
