+```javascript
+navigator.mediaDevices.getDisplayMedia().then((stream) => {
+  NAF.connection.adapter.addLocalMediaStream(stream, "screen");

+See the [Multi Streams](https://github.com/networked-aframe/networked-aframe/blob/master/examples/basic-multi-streams.html) example
+that uses a second plane with `networked-video-source="streamName: screen"` to
+show the screen share to the other participants.
+Be sure to look at the comments at the end of the html file of this example for known issues.
