+# video.js and ReactJS integration
+
+Here's a basic ReactJS player implementation.
+
+It just instantiates the video.js player on `componentDidMount` and destroys it on `componentWillUnmount`.
+
+```jsx
+import React from 'react';
+import videojs from 'video.js'
+
+export default class VideoPlayer extends React.Component {
+  componentDidMount() {
+    // instantiate video.js
+    this.player = videojs(this.videoNode, this.props, function onPlayerReady() {
+      console.log('onPlayerReady', this)
+    });
+  }
+
+  // destroy player on unmount
+  componentWillUnmount() {
+    if (this.player) {
+      this.player.dispose()
+    }
+  }
+
+  // wrap the player in a div with a `data-vjs-player` attribute
+  // so videojs won't create additional wrapper in the DOM
+  // see https://github.com/videojs/video.js/pull/3856
+  render() {
+    return (
+      <div data-vjs-player>
+        <video ref={ node => this.videoNode = node } className="video-js"></video>
+      </div>
+    )
+  }
+}
+```
+
+You can then use it like this:
+
+```jsx
+// see https://github.com/videojs/video.js/blob/master/docs/guides/options.md
+const videoJsOptions = {
+  autoPlay: true,
+  controls: true,
+  sources: [{
+    src: '/path/to/video.mp4',
+    type: 'video/mp4'
+  }]
+}
+
+return <VideoPlayer { ...videoJsOptions } />
+```
+
+Dont forget to include the video.js CSS, located at `video.js/dist/video-js.css`.
