 ## Platform guidelines
 
 We suggest you read [Human Interface Guidelines for visionOS](https://developer.apple.com/design/human-interface-guidelines/designing-for-visionos) when creating visionOS apps.
 
 It's important not to cover the translucent background with a solid color, as it helps to ground apps and make them feel like part of the environment.
 
+## API Reference
+
+### App entry point
+React native visionOS uses SwiftUI lifecycle. The app entry point is now `App.swift` file (by default it is `main.m`). This change allows us to use full capabilities of the visionOS SDK. 
+
+Here is a example from the template: 
+```swift
+// App.swift
+@main
+struct HelloWorldApp: App {
+  @UIApplicationDelegateAdaptor var delegate: AppDelegate
+  
+  var body: some Scene {
+    RCTMainWindow(moduleName: "HelloWorld")
+  }
+}
+```
+
+We are using `@UIApplicationDelegateAdaptor`, a property wrapper that allows us to use familiar `AppDelegate` in SwiftUI life cycle. 
+
+`AppDelegate` extends `RCTAppDelegate` which does most of React Native initialization.
+
+### Hover effect API
+This is a prop on `<View />` component allowing to add hover effect. It's applied to all Touchable and Pressable components by default.
+
+If you want to customize it you can use the `visionos_hoverEffect` prop, like so:
+
+```jsx
+<TouchableOpacity visionos_hoverEffect="lift">
+  <Text>Click me</Text>
+</TouchableOpacity>
+```
+
+The available options are: `lift` or `highlight`.
