+lightning-delinvoice -- Command for removing an invoice (or just its description)
+=================================================================================
 
 SYNOPSIS
 --------
 
-**delinvoice** *label* *status*
+**delinvoice** *label* *status* [*desconly*]
 
 DESCRIPTION
 -----------
 
 The **delinvoice** RPC command removes an invoice with *status* as given
-in **listinvoices**.
+in **listinvoices**, or with *desconly* set, removes its description.
 
 The caller should be particularly aware of the error case caused by the
 *status* changing just before this command is invoked!
 
+If *desconly* is set, the invoice is not deleted, but has its
+description removed (this can save space with very large descriptions,
+as would be used with lightning-invoice(7) *deschashonly*.
+
 RETURN VALUE
 ------------
 
@@ -55,6 +59,7 @@ The following errors may be reported:
   *current_status* and *expected_status* fields.
   This is most likely due to the *status* of the invoice
   changing just before this command is invoked.
+- 908: The invoice already has no description, and *desconly* was set.
