+  The Google+ platform for Android lets you authenticate a user with the same credentials they use
+  on Google every day. Once a user signs in with Google, you can create more engaging experiences
+  and drive usage of your app.
+</p>
+
+<p>
+  The <a href="https://developers.google.com/+/mobile/android/">Google+ Android API</a> allows
+  you to integrate sign-in and social features into your app.
+</p>
+

+
+<h4>Trusted authentication</h4>
+<p>
+  Google+ Sign-In is a simple, trusted, and secure way to let people sign in to your app with their
+  Google credentials and bring along their Google+ info.<br>
+  <a href="https://developers.google.com/+/mobile/android/sign-in" class="external-link">Add
+  sign-in</a>.
+</p>
+
+<h4>Access the profile and social graph</h4>
+<p>
+  Once users have signed in with Google, your app can welcome them by name, display their picture,
+  connect them with friends, and lots more.<br>
+  <a href="https://developers.google.com/+/mobile/android/people" class="external-link">Access the
+  social graph</a>.
+</p>
+
+<h4>Stand out in the stream</h4>
+<p>
+  Interactive posts is a rich way of sharing to Google+. It lets users prompt friends to take
+  specific actions in your app from a Google+ post, like "listen," "RSVP," "check-in," and over 100
+  more actions.<br>
+  <a class="external-link" href="https://developers.google.com/+/mobile/android/share">Post
+  interactive content</a>.
+</p>
+
+<h4>Recommend content</h4>
+<p>
+  Add a native +1 button so users can recommend content from your app. These endorsements can give
+  your app more credibility and help it grow faster.<br>
+  <a class="external-link" href="https://developers.google.com/+/mobile/android/recommend">Add the
+  +1 button</a>.

+<h2 id="start">Get Started</h2>
+<p>
+  The Google+ Android APIs are part of the Google Play services platform. To use Google+ features,
+  set up the Google Play services SDK in your app development project. For more information, see
+  the <a class="external-link" href=
+  "https://developers.google.com/+/mobile/android/getting-started">Getting Started</a> guide for
+  the Google+ Platform for Android
