 ### Handling RECEIPT frames
+If you include a ReceiptHandler in your message, the client will request that the server send a receipt when it has successfully processed the frame.
 ```rust
 let handler = |frame: &Frame| debug!("Received receipt for 'Hypoteneuse'", frame);
 session.message(destination, "text/plain", "Hypoteneuse".as_bytes())
