 QMK supports multiple debounce algorithms through its debounce API.

-* ```sym_eager_pk``` - debouncing per key. On any state change, response is immediate, followed by ```DEBOUNCE``` milliseconds of no further input for that key
-* ```sym_defer_pr``` - debouncing per row. On any state change, a per-row timer is set. When ```DEBOUNCE``` milliseconds of no changes have occurred on that row, the entire row is pushed. Can improve responsiveness over `sym_defer_g` while being less susceptible than per-key debouncers to noise.
-* ```sym_defer_pk``` - debouncing per key. On any state change, a per-key timer is set. When ```DEBOUNCE``` milliseconds of no changes have occurred on that key, the key status change is pushed.
-* ```asym_eager_defer_pk``` - debouncing per key. On a key-down state change, response is immediate, followed by ```DEBOUNCE``` milliseconds of no further input for that key. On a key-up state change, a per-key timer is set. When ```DEBOUNCE``` milliseconds of no changes have occurred on that key, the key-up status change is pushed.

+### Implementing your own debouncing code
+
+You have the option to implement you own debouncing algorithm with the following steps:
+
 * Set ```DEBOUNCE_TYPE = custom``` in ```rules.mk```.
 * Add ```SRC += debounce.c``` in ```rules.mk```
-* Add your own ```debounce.c```. Look at current implementations in ```quantum/debounce``` for examples.
+* Implement your own ```debounce.c```. See ```quantum/debounce``` for examples.
 * Debouncing occurs after every raw matrix scan.
-* Use num_rows rather than MATRIX_ROWS, so that split keyboards are supported correctly.
-* If the algorithm might be applicable to other keyboards, please consider adding it to ```quantum/debounce```
+* Use num_rows instead of MATRIX_ROWS to support split keyboards correctly.
+* If your custom algorithm is applicable to other keyboards, please consider making a pull request.
