 This specification outlines several standard event types, all of which are
 prefixed with ``m.``

-- m.room.name
-- m.room.topic
-- m.room.member
-- m.room.config
-- m.room.invite_join
+``m.room.name``
+  Summary:
+    Set the human-readable name for the room.
+  Type: 
+    State event
+  JSON format:
+    ``{ "name" : "string" }``
+  Example:
+    ``{ "name" : "My Room" }``
+  Description:
+    A room has an opaque room ID which is not human-friendly to read. A room alias is
+    human-friendly, but not all rooms have room aliases. The room name is a human-friendly
+    string designed to be displayed to the end-user. The room name is not *unique*, as
+    multiple rooms can have the same room name set. The room name can also be set when 
+    creating a room using ``/createRoom`` with the ``name`` key.
+
+``m.room.topic``
+  Summary:
+    Set a topic for the room.
+  Type: 
+    State event
+  JSON format:
+    ``{ "topic" : "string" }``
+  Example:
+    ``{ "topic" : "Welcome to the real world." }``
+  Description:
+    A topic is a short message detailing what is currently being discussed in the room. 
+    It can also be used as a way to display extra information about the room, which may
+    not be suitable for the room name.

+``m.room.member``
+  Summary:
+    The current membership state of a user in the room.
+  Type: 
+    State event
+  JSON format:
+    ``{ "membership" : "enum[ invite|join|leave|ban ]" }``
+  Example:
+    ``{ "membership" : "join" }``
+  Description:
+    Adjusts the membership state for a user in a room. It is preferable to use the
+    membership APIs (``/rooms/<room id>/invite`` etc) when performing membership actions
+    rather than adjusting the state directly as there are a restricted set of valid
+    transformations. For example, user A cannot force user B to join a room, and trying
+    to force this state change directly will fail. See the "Rooms" section for how to 
+    use the membership APIs.

+  JSON format:

+  Description:
+    This event is used when sending messages in a room. Messages are not limited to be text.
+    The ``msgtype`` key outlines the type of message, e.g. text, audio, image, video, etc.
+    Whilst not required, the ``body`` key SHOULD be used with every kind of ``msgtype`` as
+    a fallback mechanism when a client cannot render the message. For more information on 
+    the types of messages which can be sent, see "m.room.message msgtypes".
+
+``m.room.message.feedback``
+  Summary:
+    A receipt for a message.
+  Type:

+  JSON format:

+  Example:
+    ``{ "type": "delivered", "target_event_id": "e3b2icys" }``
+  Description:
+    Feedback events are events sent to acknowledge a message in some way. There are two
+    supported acknowledgements: ``delivered`` (sent when the event has been received) and 
+    ``read`` (sent when the event has been observed by the end-user). The ``target_event_id``
