+## CLI
+
+A CLI is provided to make debugging & testing easier. One of the utilities is the ability to publish tracks from static files.
+
+To use the publish client, download the following files to your computer:
+* [happier.ivf](https://www.dropbox.com/s/4ze93d6070s0qj7/happier.ivf?dl=0) - audio track in VP8
+* [happier.ogg](https://www.dropbox.com/s/istrnolnh7avftq/happier.ogg?dl=0) - audio track in ogg
+
+To run a peer publishing to a room, do the following:
+
+1. Ensure server is running in dev mode
+ ```
+ ./bin/livekit-server --dev
+ ```
+
+2. Create a room
+
+ ```
+ ./bin/livekit-cli create-room --room-id hello
+ ```
+
+3. Join room as publishing client
+
+ ```
+ ./ bin/livekit-cli join --room-id hello --audio <path/to/ogg> --video <path/to/ivf>
+ ```
+
+That's it, join the room with another peer id and see it receiving those tracks
