+Air Native Extension for Google Play Games Services (Android)
+======================================
+
+This is an [Air native extension](http:https://www.adobe.com/devnet/air/native-extensions-for-air.html) for [Google Play Games Services](http:https://developer.android.com/google/play-services/games.html/) SDK on Android. It has been developed by [FreshPlanet](http:https://freshplanet.com) and is used in the game [MoviePop](http:https://moviepop.net).
+
+
+Installation
+---------
+
+The ANE binary (AirGooglePlayGamesService.ane) is located in the *bin* folder. You should add it to your application project's Build Path and make sure to package it with your app (more information [here](http:https://help.adobe.com/en_US/air/build/WS597e5dadb9cc1e0253f7d2fc1311b491071-8000.html)).
+
+
+Usage
+-----
+
+You need to add the following in your AIR manifest, and replace YOUR_APP_ID by the app id of your Google Play Games Services (don't remove the "\ " at the beginning, otherwise it won't work):
+
+ <application>
+  <!-- GooglePlay Games Services -->
+  <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="\ YOUR_APP_ID" />
+  <activity android:name="com.freshplanet.googleplaygames.SignInActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" />
+ </application>
+
+
+
+```actionscript
+// Initialize
+AirGooglePlayGames.getInstance().addEventListener(AirGooglePlayGamesEvent.ON_SIGN_IN_SUCCESS, onSignInSuccess);
+AirGooglePlayGames.getInstance().addEventListener(AirGooglePlayGamesEvent.ON_SIGN_OUT_SUCCESS, onSignOutSuccess);
+AirGooglePlayGames.getInstance().addEventListener(AirGooglePlayGamesEvent.ON_SIGN_IN_FAIL, onSignInFail);
+AirGooglePlayGames.getInstance().startAtLaunch();
+
+// Update Achievement
+// with steps
+AirGooglePlayGames.getInstance().reportAchievement(achievementId, step);
+// without steps
+AirGooglePlayGames.getInstance().reportAchievement(achievementId);
+
+// Update HighScore
+AirGooglePlayGames.getInstance().reportScore(leaderbordId, value);
+
+// Show Achivements
+AirGooglePlayGames.getInstance().showStandardAchievements();
+```
+
+
+Build script
+---------
+
+Should you need to edit the extension source code and/or recompile it, you will find an ant build script (build.xml) in the *build* folder:
+
+```bash
+cd /path/to/the/ane/build
+mv example.build.config build.config
+#edit the build.config file to provide your machine-specific paths
+ant
+```
