 One instance of the camera server is meant to manage one Janus room. It does this by defining slots for cameras which are all disabled by default. To activate a slot, one has to provide a token for that slot. This token will be required to be able to send a feed on that slot. As mentioned above, only feeds that are verified in that way are shown to the receivers.
 One can also refresh the token for a given slot or simply deactivate it.
 
+## Compiling and Running the Server
+
+The camera server is written in typescript, a superset of javascript. That means that is has to be compiled before being able to start.
+To compile the code, install the typescript compiler using npm `npm install -g typescript` or apt `apt install node-typescript`.
+Navigate into the `camera-server` folder and run `tsc`. This will compile the files into a newly created folder `dist`.
+
+Once the code is compiled, the server can be started with `node server.js` in the `dist` folder.
