 Clients can send 3 types of messages, which must be JSON arrays, according to the following patterns:
 
-  * `["EVENT", <event JSON as defined above>`], used to publish events.
-  * `["REQ", <subscription_id>, <filters JSON>...`], used to request events and subscribe to new updates.
+  * `["EVENT", <event JSON as defined above>]`, used to publish events.
+  * `["REQ", <subscription_id>, <filters JSON>...]`, used to request events and subscribe to new updates.
   * `["CLOSE", <subscription_id>]`, used to stop previous subscriptions.
 
 `<subscription_id>` is a random string that should be used to represent a subscription.
 
 `<filters>` is a JSON object that determines what events will be sent in that subscription, it can have the following attributes:
 
-```

 {
   "ids": <a list of event ids or prefixes>,
   "authors": <a list of pubkeys or prefixes, the pubkey of an event must be one of these>,
