+# The default keymap for Duet
+
+Since this is a very irregular keyboard with unique use cases, the keymap should be customized to meet one's needs and to match the requirements of the corresponding display software (if any).  
+By default, all keys send `KC_0` to simply notify the host that an arbitrary key has been pressed.
