+#### Setup
+
+1. You'll need to update your `AppDelegate.swift` to handle push check the example app [here](./example/ios/AppDelegate.swift) for an example.
+2. If your AppDelegate is in Objective-C (`.mm|.m|.h`), create a new `AppDelegate.swift` file and bridging header then delete the Objective-C AppDelegate and main.m file. Finally copy the contents of the example app's `AppDelegate.swift` and bridge header to your project.

+## Testing
+
+If you run the example app, you can test push notifications by running the following command:
+
+```sh
+yarn push
+```
+
+This will use the [payload.json](./example/payload.json) file to send a push notification to the device. You can modify the payload to test different scenarios.
