+Using encoder mapping pumps events through the normal QMK keycode processing pipeline, resulting in a _keydown/keyup_ combination pushed through `process_record_xxxxx()`. To configure the amount of time between the encoder "keyup" and "keydown", you can add the following to your `config.h`:
+
+```c
+#define ENCODER_MAP_KEY_DELAY 10
+```
+
+?> By default, the encoder map delay matches the value of `TAP_CODE_DELAY`.

 ## Callbacks
 
 When not using `ENCODER_MAP_ENABLE = yes`, the callback functions can be inserted into your `<keyboard>.c`:
