The configuration is simple. Navigate to the „Smart Banner“ dashboard page.
Here you can customize the texts and choose an app icon from the file manager.
In the system-specific sections, you can can announce your app's.
For Android you need the package name also called App-Id. The package name is mostly in the notation „com.vendor.appname“. You can find the app id in the Google Play Console.
For the announcement of an iOS app you also need the numeric App-Id. You can find the app id on iTunes Connect (https://itunesconnect.apple.com/).
Windows Phone apps behaves similarly. Log into the Microsoft Developer Center and copy App Id and the Family Package Name.
After you have made your app known in the add-on settings and you have configured the texts you are done with the setup. Congratulations.
