+# simulcast
+demonstrates of how to handle incoming track with multiple simulcast rtp streams and show all them back.
+
+The browser will not send higher quality streams unless it has the available bandwidth. You can look at
+the bandwidth estimation in `chrome://webrtc-internals`. It is under `VideoBwe` when `Read Stats From: Legacy non-Standard`
+is selected.
+
+## Instructions
+### Download simulcast
+```
+go install github.com/pion/webrtc/v4/examples/simulcast@latest
+```
+
+### Open simulcast example page
+[jsfiddle.net](https://jsfiddle.net/tz4d5bhj/) you should see two text-areas and two buttons: `Copy browser SDP to clipboard`, `Start Session`.
+
+### Run simulcast, with your browsers SessionDescription as stdin
+In the jsfiddle the top textarea is your browser's Session Description. Press `Copy browser SDP to clipboard` or copy the base64 string manually.
+We will use this value in the next step.
+
+#### Linux/macOS
+Run `echo $BROWSER_SDP | simulcast`
+#### Windows
+1. Paste the SessionDescription into a file.
+1. Run `simulcast < my_file`
+
+### Input simulcast's SessionDescription into your browser
+Copy the text that `simulcast` just emitted and copy into second text area
+
+### Hit 'Start Session' in jsfiddle, enjoy your video!
+Your browser should send a simulcast track to Pion, and then all 3 incoming streams will be relayed back.
+
+Congrats, you have used Pion WebRTC! Now start building something cool
