 ### Creating and configuring a map
 
-Configuring the map can be done either by passing a `GoogleMapOptions` instance 
-to initialize the map, or by passing a `MapProperties` object into the `GoogleMap`
-composable.
+Configuring the map can be done by passing a `MapProperties` object into the 
+`GoogleMap` composable. For anything not available in `MapProperties` (typically 
+anything that can only be provided once - like map ID), provide a 
+`GoogleMapOptions` instance in the `googleMapOptionsFactory` properties instead.
 
 ```kotlin
-// Initialize map by providing a googleMapOptionsFactory
-GoogleMap(
-    googleMapOptionsFactory = {
-        GoogleMapOptions().mapId("MyMapId")
-    }
-)

 ### Controlling a map's camera
 
 Camera changes and updates can be observed and controlled via `CameraPositionState`.
 
+**Note**: `CameraPositionState` is the source of truth for anything camera 
+related. So, providing a camera position in `GoogleMapOptions` will be 
+overridden by `CameraPosition`.
