 The following optional parameters can be passed when retrieving previously sent messages:
 
-| Parameter | Description |
-| --------- | ----------- |
-| `start` | Earliest time to retrieve messages from, as a unix timestamp in milliseconds. Messages with a timestamp equal to, or greater than, this value will be returned. |
-| `end` | Latest time to retrieve messages from, as a unix timestamp in milliseconds. Messages with a timestamp less than this value will be returned. |
-| `orderBy` | The order in which to retrieve messages from; either `oldestFirst` or `newestFirst`. |
-| `limit` | Maximum number of messages to be retrieved per page, up to 1,000. |
+| Parameter | Description | Default |
+| --------- | ----------- | ------- |
+| start | Earliest time to retrieve messages from, as a unix timestamp in milliseconds. Messages with a timestamp equal to, or greater than, this value will be returned. | Earliest available message |
+| end | Latest time to retrieve messages from, as a unix timestamp in milliseconds. Messages with a timestamp less than this value will be returned. | Current time |
+| orderBy | The order in which to retrieve messages from; either `oldestFirst` or `newestFirst`. | `newestFirst` |
+| limit | Maximum number of messages to be retrieved per page, up to 1,000. | 100 |

+### Understanding message ordering <a id="understanding-message-ordering"/>
+
+The `orderBy` parameter determines both *which* messages are retrieved and their return order:
+
+| Order | Retrieves | Returns | Use case |
+| ----- | --------- | ------- | -------- |
+| `newestFirst` (default) | Most recent messages | `[newest, ..., oldest]` | Standard chat UIs |
+| `oldestFirst` | Oldest messages from room start | `[oldest, ..., newest]` | Archives, exports, admin tools |
+
+**For typical chat applications:** Use `newestFirst` (default) to get recent messages, then reverse the result for showing newest message at the bottom of the UI.
 
 ## Retrieve messages sent prior to subscribing <a id="subscribe"/>
 
-Users can also retrieve historical messages that were sent to a room before the point that they registered a listener by [subscribing](/docs/chat/rooms/messages#subscribe). The order of messages returned is from most recent, to oldest. This is useful for providing conversational context when a user first joins a room, or when they subsequently rejoin it later on. It also ensures that the message history they see is continuous, without any overlap of messages being returned between their subscription and their history call.
+Retrieve historical messages sent before subscribing using `historyBeforeSubscribe()`. Messages are returned in `newestFirst` order. This is useful for providing conversational context when a user joins or rejoins a room, ensuring continuous message history without overlap.
