 If you want to use custom protocol, you should put subclass of [protocol class](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes) in the protocol keyword argument of `sanic.run()`. The constructor of custom protocol class gets following keyword arguments from Sanic.
 
-* loop

 `loop` is an asyncio compatible event loop.
 
-* connections
+* connections  
 `connections` is a `set object`  to  store protocol objects.
 When Sanic receives `SIGINT` or `SIGTERM`, Sanic executes `protocol.close_if_idle()` for a `protocol objects` stored in connections.
 
-* signal
+* signal  
 `signal` is a `sanic.server.Signal object` with `stopped attribute`.
 When Sanic receives `SIGINT` or `SIGTERM`, `signal.stopped` becomes `True`.
 
-* request_handler
+* request_handler  
 `request_handler` is a coroutine that takes a `sanic.request.Request` object and a `response callback` as arguments.
 
-* error_handler
+* error_handler  
 `error_handler` is a `sanic.exceptions.Handler` object.
 
-* request_timeout
+* request_timeout  
 `request_timeout` is seconds for timeout.
 
-* request_max_size
+* request_max_size  
 `request_max_size` is bytes of max request size.
