-Push notifications on Android are managed and dispatched using [Google's GCM service](https://developers.google.com/cloud-messaging/gcm) (now integrated into Firebase). The following installation steps are a TL;DR of [Google's GCM setup guide](https://developers.google.com/cloud-messaging/android/client). You can follow them to get GCM integrated quickly, but we recommend that you will in the very least have a peek at the guide's overview.

+#### Step #1: Subscribe to Google's FCM
 
-To set GCM in your app, you must first create a Google API-project and obtain a **Sender ID** and a **Server API Key**. If you have no existing API project yet, the easiest way to go about in creating one is using [this step-by-step installation process](https://developers.google.com/mobile/add); Use [this tutorial](https://code.tutsplus.com/tutorials/how-to-get-started-with-push-notifications-on-android--cms-25870) for insturctions.
+To set FCM in your app, you must first create a google-services.json file. If you have no existing API project yet, the easiest way to go about in creating one is using [this step-by-step installation process](https://firebase.google.com/docs/android/setup);

+#### Step #2: Copy google-services.json
 
-Once obtained, bundle the Sender ID onto your main `manifest.xml` file:
+After creating google-services.json, copy it into your project's android/app folder.
 
+#### Step #3: Add google-services package to Project/build.gradle
 ```gradle
-<manifest>

-	<application>
-	...
-		// Replace '1234567890' with your sender ID.
-		// IMPORTANT: Leave the trailing \0 intact!!!
