title: How to add custom library to Android Studio 2.2.3
body: <p>I just started using Android Studio and I would like to add an open source library to my project. I looked a lot over the internet, but I couldn't find a way to make my project compile and to make the library's classes visible.</p>
  
  <p>This is the library I would like to include: <a href="https://github.com/TangoAgency/material-intro-screen?utm_source=android-arsenal.com&amp;utm_medium=referral&amp;utm_campaign=4368" rel="nofollow noreferrer">https://github.com/TangoAgency/material-intro-screen?utm_source=android-arsenal.com&amp;utm_medium=referral&amp;utm_campaign=4368</a></p>
  
  <p>On the readme it says as the first thing to add a gradle dependency:</p>
  
  <pre><code>dependencies {
     compile 'agency.tango.android:material-intro-screen:{latest_release}'
  }
  </code></pre>
  
  <p>But it seems to me that there is something more to do before that... It's just I don't know what.</p>
