 ## WebsocketServer
 
-The WebsocketServer takes two arguments: a `port` and a `hostname`.
-By default the localhost `127.0.0.1` is used. However if you want to be able and connect
-to the server from the network you need to pass `0.0.0.0` as hostname e.g. `WebsocketServer(13254, host='0.0.0.0')`.
+The WebsocketServer can be initialized with the below parameters.
+
+*`port`* - The port clients will need to connect to.
+
+*`host`* - By default the `127.0.0.1` is used which allows connections only from the current machine. If you wish to allow all network machines to connect, you need to pass `0.0.0.0` as hostname.
+
+*`loglevel`* - logging level to print. By default WARNING is used. You can use `logging.DEBUG` or `logging.INFO` for more verbose output.
