 ### Modal component quirks
 
-Edge-to-edge support for the built-in [`Modal`](https://reactnative.dev/docs/modal) component will be available in [React Native 0.77](https://github.com/facebook/react-native/pull/47254). Meanwhile, we recommend using the [react-navigation modals](https://reactnavigation.org/docs/modal), or the [`expo-router` modal screens](https://docs.expo.dev/router/advanced/modals/#modal-screen-using-expo-router).

 ### Keyboard management
 
 Enabling edge-to-edge display disrupts Android keyboard management (`android:windowSoftInputMode="adjustResize"`), requiring an alternative solution. While [`KeyboardAvoidingView`](https://reactnative.dev/docs/keyboardavoidingview) is a viable option, we recommend using [react-native-keyboard-controller](https://github.com/kirillzyusko/react-native-keyboard-controller) for its enhanced capabilities.
 
+### Transparent navigation bar
+
+This library follows the default [AndroidX `enableEdgeToEdge`](https://developer.android.com/develop/ui/views/layout/edge-to-edge) behavior. The system bars are transparent, except in 3-button navigation mode, where the navigation bar becomes translucent (semi-opaque). Its color adjusts based on your app's light or dark theme.
