 ### Advanced Usage
 
+#### Custom player controls
+
+By default ReactPlayer is a chromeless player. By setting the `controls` prop to `true`, you can enable the native controls for the player. However, the controls will look different for each player. The ones based on HTML5 media players will look like the native controls for that browser, while the ones based on third-party players will look like the native controls for that player.
+
+```jsx
+<ReactPlayer src='https://www.youtube.com/watch?v=LXb3EKWsInQ' controls />
+```
+
+If you like to add your own custom controls in a convenient way, you can use
+[Media Chrome](https://github.com/muxinc/media-chrome). Media Chrome is a library that provides a set of UI components that can be used to quickly build custom media controls.
+
+##### Simple example ([Codesandbox](https://codesandbox.io/p/sandbox/react-player-media-chrome-simple-nl3pg4))
+
+```tsx
+import ReactPlayer from "react-player";
+import {
+  MediaController,
+  MediaControlBar,
+  MediaTimeRange,
+  MediaTimeDisplay,
+  MediaVolumeRange,
+  MediaPlaybackRateButton,
+  MediaPlayButton,
+  MediaSeekBackwardButton,
+  MediaSeekForwardButton,
+  MediaMuteButton,
+  MediaFullscreenButton,
+} from "media-chrome/react";
+
+export default function Player() {
+  return (
+    <MediaController
+      style={{
+        width: "100%",
+        aspectRatio: "16/9",
+      }}
+    >
+      <ReactPlayer
+        slot="media"
+        src="https://stream.mux.com/maVbJv2GSYNRgS02kPXOOGdJMWGU1mkA019ZUjYE7VU7k"
+        controls={false}
+        style={{
+          width: "100%",
+          height: "100%",
+          "--controls": "none",
+        }}
+      ></ReactPlayer>
+      <MediaControlBar>
+        <MediaPlayButton />
+        <MediaSeekBackwardButton seekOffset={10} />
+        <MediaSeekForwardButton seekOffset={10} />
+        <MediaTimeRange />
+        <MediaTimeDisplay showDuration />
+        <MediaMuteButton />
+        <MediaVolumeRange />
+        <MediaPlaybackRateButton />
+        <MediaFullscreenButton />
+      </MediaControlBar>
+    </MediaController>
+  );
+}
+```
+
 #### Light player
 
 The `light` prop will render a video thumbnail with simple play icon, and only load the full player once a user has interacted with the image. [Noembed](https://noembed.com) is used to fetch thumbnails for a video URL. Note that automatic thumbnail fetching for Facebook, Wistia, Mixcloud and file URLs are not supported, and ongoing support for other URLs is not guaranteed.
