+## Push Notifications Example
+
 This app gives you a brief understanding of how Ably's Push Notifications work. 
 You will need a real iOS device to test this functionality.
 
 - First, go to https://ably.com/accounts/, create an app and copy API key from API Keys tab of the app's dashboard.
 - Go to the `Notifications` tab of the Ably's app dashboard and scroll to the `Push Notifications Setup` section. Press `Configure Push` and follow the instructions there.
 - Insert it instead of an empty string in the `key` property's value inside the `AblyHelper` class.
-- Make sure you've selected your development team in the `Signing & Capabilities` tab of the Xcode project target settings and all the provisioning profiles created without errors.
+- Make sure you've selected your development team in the `Signing & Capabilities` tab of the Xcode project target settings and all the provisioning profiles created without errors (update the `bundle-id` for the `AblyPushExample` target as needed).
 - Build and Run the app on your device.
 - Hit "Activate" button, then hit "Print Token". You should see "IDENTITY TOKEN: exists" printed in the debug output window.
 - Hit "Device Details" to display Ably push device registration info after successful activation.
 - Go to the `Notifications` tab of the Ably's app dashboard again and scroll to the `Push Inspector` section. Fill in `Title` and `Body` fields of the push notification. Then insert "basic-apns-example" in the `Client ID` field and press enter. Then hit "Push to client" button. You should now see the notification on the screen of your device.
-- Also you can send notifications from the app itself if you tick `Push Admin` capability in your API key settings in the app's dashboard. Just hit "Send Push" button to send a predefined push notification which is also will be displayed on your device's screen right away. You can change this behavior in the `UNUserNotificationCenterDelegate` extension for the `AblyHelper` by editing `completionHandler([.banner, .sound])` line of code.

+### Location pushes
+
+* In order to use this capability (starting from iOS 15), you need to apply for the special entitlement on the Apple's developer portal. Follow instructions [here](https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_developer_location_push) on how to do that.
+
+* Update the `bundle-id` for the `AblyPushExample` and `AblyLocationPush` targets as needed.
+
+* To receive location push notifications you need to request another device token specifically for the location pushes purpose. You do so by calling `CLLocationManager.startMonitoringLocationPushes(completion:)` within a `ARTPushRegistererDelegate.didActivateAblyPush(:)` delegate method (which is a callback for the `ARTRealtime.push.activate()` call).
+
+* Once you receive the location push token, save it by calling a new `ARTPush.didRegisterForLocationNotifications(withDeviceToken:realtime:)` method (note the "Location" word in the name of this method). Ably will call the `ARTPushRegistererDelegate.didUpdateAblyPush:` callback on a successful or failed attempt to save the token.
+
+* Use the "Location push events" button in the example app to open a list of received location pushed notifications.

 Starting with iOS 15, Apple supports power efficient way to request location trough [location push service extension](https://developer.apple.com/documentation/corelocation/creating_a_location_push_service_extension).
 
-To use this new functionality you should obtain Apple entitlments, create location push service extension and make some tweaks in your push notifications code within your app:
-
-* Add Apple location pushes entitlments into your project ("AblyLocationPush" folder).
-
-* In addition to saving your regular device token by calling `ARTPush.didRegisterForRemoteNotifications(withDeviceToken:realtime:)` you should request another device token specifically for the location pushes purpose. You do so by calling `CLLocationManager.startMonitoringLocationPushes(completion:)` within a `ARTPushRegistererDelegate.didActivateAblyPush(:)` delegate callback or whenever is appropriate in your app.
-
-* Once you receive the location push token, save it by calling a new `ARTPush.didRegisterForLocationNotifications(withDeviceToken:realtime:)` method (note the "Location" word in the name of this method).
-
-* To see received location push notifications in the UI you need to update both "AblyPushExample.entitlements" file and the file you received from Apple and add appropriate value under the `com.apple.security.application-groups` key ("group.{your_bundle_identifier}"). It is because application groups is the only way app and its location push extension can exchange information.

-See [embed APNs example app](https://github.com/ably/ably-cocoa/tree/main/Examples/AblyPush) for more details on how this should be implemented.
+Refer to the [embed APNs example app](https://github.com/ably/ably-cocoa/blob/main/Examples/AblyPush/README.md) on how this can be implemented.
 
 Only one instance of `ARTRest` or `ARTRealtime` at a time must be [activated for receiving push notifications](https://www.ably.com/docs/general/push/activate-subscribe). Having more than one activated instance at a time may have unexpected consequences.
