+The app is using the official Jetpack Compose framework by Google. Crashes of the app are detected

+Google Play, a self-hosted Sentry instance is used. Feature Flags are possible and implemented via
+a self-hosted Unleash instance.
 
 ## Setup
 
-First of all you should copy the `key.properties.example` file in the root directory and copy the
-contents into a `key.properties` (for release) or a `dev.properties` (for debug) file. With those 
-properties the main keys and URLs of the application can be set.
+Personalised properties can be configured in the app-level `build.gradle` file.
 
 | Property name        | Usage                                       | Mandatory |

-### Unleash
-
-Träwelldroid uses feature toggles with [Unleash](https://getunleash.io) so that features already can
-be implemented although they aren't rolled out on depending APIs yet. The official Träwelldroid
-build uses a self-hosted Unleash variant hosted in Germany.
