title: How to use Processing 3 on IntelliJ IDEA?
body: <p>I'd like to use the <strong>IntelliJ IDEA IDE</strong> to develop some app using <strong>Processing 3</strong>. How can I do that ?</p>
  
  <p>There are only tutorials on how to use Processing 2, but I think things have changed enough so that those tutorials do not work anymore.</p>
  
  <p>Thank you</p>
