-When not using `ENCODER_MAP_ENABLE = yes`, the callback functions can be inserted into your `<keyboard>.c`:
+?> [**Default Behaviour**](https://github.com/qmk/qmk_firmware/blob/master/quantum/encoder.c#L79-#L98): all encoders installed will function as volume up (`KC_VOLU`) on clockwise rotation and volume down (`KC_VOLD`) on counter-clockwise rotation. If you do not wish to override this, no further configuration is necessary.
 
-?> Those who are adding new keyboard support where encoders are enabled at the keyboard level should include basic encoder functionality at the keyboard level (`<keyboard>.c`) using the `encoder_update_kb()` function, that way it works for QMK Configuator users and exists in general.
+If you would like the alter the default behaviour, and are not using `ENCODER_MAP_ENABLE = yes`, the callback functions can be inserted into your `<keyboard>.c`:
