title: How to create a guided tour for an android application
body: <p>A couple of months ago I bought myself an HTC ONE X. I admired they way they guide the user in taking his first steps in the phone with interactive widgets and help functions.</p>
  
  <p>I would like to add this kind of functionality to Rogerthat, the app we are building, but I wonder if there are tools / libraries that can help me achieve this?</p>
