+There are three different build flavors, `googleNormal`, `fossNormal` and `googleAutomotive`.
+- The `foss` variant only uses Mapbox data and should run on most Android devices, even without
+  Google Play Services.
+- The `google` variants also include access to Google Maps data.
+    - `googleNormal` is intended to run on smartphones and tablets, and also includes the Android
+      Auto app for use on the car display.
+    - `googleAutomotive` variant is intended to be installed directly on car infotainment systems
+      using the Google-flavored Android Automotive OS. It does not provide the usual smartphone UI.

 We also have a special [documentation page](doc/android_auto.md) on how to test the Android Auto
 app.
