 Advertising implementation, specifically for AdMob (at present)
 
-**NOTE: The demo has been updated (on July 26th, 2022) to align it with the Firebase iOS SDK v8.15.0**. See the [Libraries > iOS](#ios) section below.
+**NOTE: The demo has been updated (on Oct 9th, 2023) to align it with the Firebase iOS SDK v10.8.0**. See the [Libraries > iOS](#ios) section below.
 
-## Project Configuration
+## Supported Delphi versions
+
+Delphi 11.x. It _should_ also work in Delphi 10.4.2, and perhaps earlier.

+## Project configuration
 
 ### Component
 
 **Please install the TAdMobBannerAd component first** (before even loading the demo)
 
-The package can be found [here](https://github.com/DelphiWorlds/Kastri/tree/main/Packages/D110) 
+A package containing the component is available [here](https://github.com/DelphiWorlds/Kastri/blob/master/Packages/KastriAdMob.dproj)
 
 ### Libraries
 
 #### Android
 
-If creating your own project, you will need to add the [`dw-admob.jar`](https://github.com/DelphiWorlds/Kastri/blob/master/Lib/dw-admob.jar) file to the Libraries node under the Android platform in Project Manager
+If creating your own project, you will need to add the supporting library:
+
+* Delphi 10.4 and 11: [`dw-admob.jar`](https://github.com/DelphiWorlds/Kastri/blob/master/Lib/dw-admob.jar) 
+
+to the Libraries node under the Android platform in Project Manager
+
+**Note**:
+
+Due to a bug in Delphi 11.3 **ONLY**, if you need to compile for Android 64-bit, you will either need to apply [this workaround](https://docs.code-kungfu.com/books/hotfix-113-alexandria/page/fix-jar-libraries-added-to-android-64-bit-platform-target-are-not-compiled) (which will apply to **all** projects), **OR** copy the jar file(s) to _another folder_, and add them to the Libraries node of the Android 64-bit target. (Adding the same `.jar` file(s) to Android 64-bit does _not_ work)****
 
 When using Delphi 10.4.x, you will need to add other libraries and disable some default libraries, as per this screenshot:

+Note that **Kastri support for Delphi 10.4 will cease** once Delphi 12 has been released. The files will still be available, however.
+
 #### iOS
 
-AdMob support in Kastri has now been aligned with the latest compatible version of the Firebase SDK for iOS, which is version 8.15.0. Please [download the SDK from here](https://github.com/firebase/firebase-ios-sdk/releases/download/v8.15.0/Firebase.zip), and unzip it somewhere, preferably in a folder that can be common to other projects that use the SDK. Create an [Environment Variable User System Override](https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Environment_Variables) called Firebase, and set it to the folder where the SDK was unzipped to. This corresponds to the `$(Firebase)` macro in the Project Options of the demo.

-In order to compile successfully for iOS, it's also necessary to add the following frameworks to the iOS SDK:
+1. Add [Swift Support Files in Delphi's SDK Manager](https://github.com/DelphiWorlds/HowTo/tree/main/Solutions/AddSwiftSupport) (follow the link for instructions)
+2. Add the following frameworks to the iOS SDK in Delphi's SDK Manager:
 
-* AVKit
+* Accessibility
+* Combine
+* AdServices
 * CoreMotion
+* DataDetection
+* UniformTypeIdentifiers
+
+[This link](https://github.com/DelphiWorlds/HowTo/tree/main/Solutions/AddSDKFrameworks) describes how to add the frameworks.
+
+If, for whatever reason, you need to drop back to Firebase v8.15 SDK, in the Project Options you will need to:
+
+1. Add `FIREBASE_PRE_V10` to the Conditional Defines
+2. Modify the Framework Search Path value for iOS Device 64 target to:
+   ```
+   $(Firebase)\FirebaseAnalytics\GoogleAppMeasurement.xcframework\ios-arm64_armv7;$(Firebase)\FirebaseAnalytics\GoogleAppMeasurementIdentitySupport.xcframework\ios-arm64_armv7;$(Firebase)\FirebaseAnalytics\GoogleUtilities.xcframework\ios-arm64_armv7;$(Firebase)\FirebaseAnalytics\nanopb.xcframework\ios-arm64_armv7;$(Firebase)\FirebaseAnalytics\PromisesObjC.xcframework\ios-arm64_armv7;$(Firebase)\Google-Mobile-Ads-SDK\GoogleMobileAds.xcframework\ios-arm64_armv7;$(Firebase)\Google-Mobile-Ads-SDK\UserMessagingPlatform.xcframework\ios-arm64_armv7
+   ```
 
-[This article](https://delphiworlds.com/2013/10/adding-other-ios-frameworks-to-the-sdk-manager/) is a guide as to how to add the frameworks.
