-**Default configuration values**: See the [SDS Implementation Suggestions](https://github.com/vacp2p/rfc-index/blob/main/vac/raw/sds.md#sdk-usage-reliablechannel) section for recommended default values for `ReliableChannelOptions`.
-
-**`channel_id` and `sender_id`**:
-
-The `channel_id` MUST be the same for all participants in a channel.
-The `sender_id` SHOULD be unique for each participant and SHOULD be persisted between sessions to ensure proper acknowledgement tracking.
-
-**`content_topic`**:
-
-A Reliable Channel uses a unique content topic. This ensure that all messages are retrievable.
-
-**`options.auto_start`**:
-
-If set to `true` (default), the Reliable Channel SHOULD automatically call `start()` during creation.
-If set to `false`, the application MUST call `start()` before the channel will process messages.
-
-**`options.query_on_connect`**:
-
-If set to `true` (default) and the Waku node has store capability,
-the Reliable Channel SHOULD automatically query the store for missing messages when connecting to store nodes.
-This helps ensure message consistency when participants come online after being offline.
