+## Updating application icon and launch screen
+
+Since iOS 11, Apple requires the app icon to be added in the form of an `Assets.car` file that needs to be created via Xcode (or online tools created by the developer community). The details are explained in great detail by our friends from distriqt, so please refer to [their tutorial][4] for the details.
+
+The same document also explains how to set up your launch screen (i.e. `LaunchScreen.storyboard`) – but beware that you only need to set that up if you're using a commercial version of AIR. If you're on the 'Free Tier', Harman will show a splash screen anyway, so don't bother with it.
+
+In any case, have a look at the 'util' folder of the Starling download to find the Xcode project that was used to create icons and launch screen for the scaffold project.
+Together with above's tutorial, you should be able to adapt it to your needs.
+
+Android nowadays requires 'adaptive icons' for its apps, which means that they are split up into a foreground and a background image.
+Those files are most easily created with _Android Studio_ and then imported into your app via a 'resource folder'.
+
+Again, I want to forward you to the respective [tutorial][5] from distriqt.
+The scaffold project has its resource folder inside `system/res`; the new `resdir` element inside the application XML will tell AIRs packaging tool where to find them.
