 ### Initialization
+
+#### Prefab
+Located in the `com.onesignal.unity.core` package we've include a simple prefab which initializes OneSignal. You can easily find it using the Asset search bar
+to find `OneSignalController.prefab` and making sure to select **All** or **In Packages** for your search option. Drag the prefab into your very first scene, fill 
+in the **App Id**, and you are immediately ready to go!
+
+#### Code
 To get started add the following code in an appropriate place such as the `Start` method of a `MonoBehaviour` early in your application's lifecycle.
 ```C#
 // Replace 'YOUR_ONESIGNAL_APP_ID' with your OneSignal App ID from app.onesignal.com
-OneSignal.StartInit("YOUR_ONESIGNAL_APP_ID").EndInit();
+OneSignal.Default.Initialize("YOUR_ONESIGNAL_APP_ID");
 ```
