+# Expo
+
+## Expo plugin
+From version `6.3.1`, we have added support for expo plugin. You can configure `react-native-video` properties in `app.json` (or `app.config.json` or `app.config.js`) file.
+It's useful when you are using `expo` managed workflow (expo prebuild) as it will automatically configure `react-native-video` properties in native part of the expo project.
+
+```json
+// app.json
+{
+  {
+  "name": "my app",
+  "plugins": [
+    [
+      "react-native-video",
+      {
+        // ...
+        "enableNotificationControls": true,
+        "androidExtensions": {
+          "useExoplayerRtsp": false,
+          "useExoplayerSmoothStreaming": false,
+          "useExoplayerHls": false,
+          "useExoplayerDash": false,
+        }
+        // ...
+      }
+    ]
+  ]
+}
+}
+```
+
+## Expo Plugin Properties
+
+| Property | Type | Default | Description |
+| --- | --- | --- | --- |
+| enableNotificationControls | boolean | false | Add required changes on android to use notification controls for video player |
+| enableBackgroundAudio | boolean | false | Add required changes to play video in background on iOS |
+| enableADSExtension | boolean | false | Add required changes to use ads extension for video player |
+| enableCacheExtension | boolean | false | Add required changes to use cache extension for video player on iOS |
+| androidExtensions | object | {} | You can enable/disable extensions as per your requirement - this allow to reduce library size on android |
