+Get Started with Google Analytics for Firebase
+==============================================
+
+Thank you for installing the Unity Google Analytics for Firebase SDK. The
+[Analytics guide](https://firebase.google.com/docs/analytics/unity/start)
+provides instructions to configure a Unity project.
+
+# Overview
+
+[Google Analytics for Firebase](https://firebase.google.com/products/analytics/)
+collects usage and behavior data for your game.
+
+The SDK logs two primary types of information:
+* *Events*. What is happening in your game, such as user actions, system events,
+  or errors.
+* *User properties*. Attributes you define to describe segments of your user
+  base, such as language preference or geographic location.
+
+Google Analytics automatically logs some events and user properties; you don't
+need to add any code to enable them. If your app needs to collect additional
+data, you can set up to 25 different Analytics user properties and log up to
+500 different Analytics event types in your app. There is no limit on the total
+volume of events your app logs.
+
+# Using the Sample
+
+This SDK is distributed with a sample project under the
+`Assets/Firebase/Sample/Analytics` directory. To configure and run the sample,
+follow the instructions in `Assets/Firebase/Sample/Analytics/readme.md`.
+
+# Demos
+
+[Mecha Hamster](https://github.com/google/mechahamster) is provided as a demo
+which showcases the integration of multiple Firebase features within a single
+game.  The source is available on
+[GitHub](https://github.com/google/mechahamster), and the live application
+is available for iOS on the
+[App Store](https://itunes.apple.com/us/app/mechahamster/id1286046770?mt=8&ign-mpt=uo%3D4)
+and for Android on the
+(Google Play Store)[https://play.google.com/store/apps/details?id=com.google.fpl.mechahamster&hl=en].
