 OneSignal makes engaging customers simple and is the fastest, most reliable service to send push notifications, in-app messages, SMS, and emails.
 
-This project demonstrates how to send a push notification from a [Supabase Edge Function](https://supabase.com/docs/guides/functions). Use this sample integration as a reference for your own edge function implementation.

 ## Setup OneSignal App
 
+1. From the OneSignal Dashboard, select **New App/Website** to create an app.
+![Select New App/Website to create new app](assets/configure-android/01-create-new-app.png)
+2. Name app and choose the **Android** platform to setup. ![Onesignal platform configuration](assets/configure-android/02-configure-android.png)
+3. Enter FCM credentials for the Firebase project you want to handle Android notifications and choose **Save & Continue**. ![FCM configuration form](assets/configure-android/03-save-fcm-details.png)
+
 ### Setup iOS Platform
 
-### Setup Android Platform
+iOS configuration requires substantially more effort to integrate due to needing signed certs from Apple. Due to this fact, follow [this guide](https://github.com/OneSignalDevelopers/OneSignal-Flutter-Sample/blob/main/docs/obtaining-ios-push-cert.md) for detailed instructions on creating the certificate needed to use Apple's Push Notification Service ([APNs](https://developer.apple.com/documentation/usernotifications/registering_your_app_with_apns)).
+
+After you have the certificate, head to the OneSignal Dashboard
+
+1. Choose **Settings -> Platforms**
+2. **Activate** the iOS card
+![Platform settings](assets/configure-ios/01-activate-apple-platform.png)
+3. Upload your certificate and enter the password you used to encrypt it. If you didn't set a password, leave the password input blank. ![Apple iOS (APNs) Configuration form](assets/configure-ios/02-apns-configuration.png)
