 To listen for message events:
 
 ```javascript
-client.on("Room.timeline", function (event, room, toStartOfTimeline) {
+client.on(sdk.RoomEvent.Timeline, function (event, room, toStartOfTimeline) {

 By default, the `matrix-js-sdk` client uses the `MemoryStore` to store events as they are received. For example to iterate through the currently stored timeline for a room:
 
 ```javascript
-Object.keys(client.store.rooms).forEach((roomId) => {
-    client.getRoom(roomId).timeline.forEach((t) => {
+Object.keys(client.store.getRooms()).forEach((roomId) => {
