+///
+/// # Handling Messages
+///
+/// `OnionMessenger` implements [`OnionMessageHandler`], making it responsible for either forwarding
+/// messages to peers or delegating to the appropriate handler for the message type. Currently, the
+/// available handlers are:
+/// * [`OffersMessageHandler`], for responding to [`InvoiceRequest`]s and paying [`Bolt12Invoice`]s
+/// * [`CustomOnionMessageHandler`], for handling user-defined message types
+///
+/// # Sending Messages
+///
+/// [`OnionMessage`]s are sent initially using [`OnionMessenger::send_onion_message`]. When handling
+/// a message, the matched handler may return a response message which `OnionMessenger` will send
+/// on its behalf.
