+## Screen sharing
+
+Since there is no good support for WebRTC screensharing with wayland, a virtual
+webcam device can be used.
+
+    :::shell
+    sudo modprobe v4l2loopback exclusive_caps=1 card_label=screensharing # only has to be done once
+    wf-recorder --muxer=v4l2 --codec=rawvideo --file=/dev/video2 -x yuv420p # adjust /dev/video2 to the actual device
+
+To remove the virtual webcam device run `sudo modprobe -r v4l2loopback`
