 ## Publishing
 
 To send an event to the Relay, Clients send a broadcast message in the format: 
 
-  * `["EVENT", <JSON-serialized string of the event>]`
+```js 
+["EVENT", <string JSON-serialized event>]
+```
 
 Relays reply with an ACK message in the format of: 
 
-  * `["OK", <event_id>, <accepted>, <prefix>:<message>]`
+```js 
+["OK", <string event_id>, <bool accepted>, <string prefix:message>]
+```
 
 `OK` messages MUST be sent in response to `EVENT` messages received from clients, they must have the 3rd parameter set to `true` when an event has been accepted by the relay, `false` otherwise. The 4th parameter MUST always be present, but MAY be an empty string when the 3rd is `true`.
