 * **Bootmagic reset**: Hold down the top left key on the left half (or the top right right key on the right half) and plug in the controller on that side.
 * **Physical reset button**: Briefly press the reset button soldered on the PCB.
 * **Keycode in layout**: Press the key mapped to `RESET` if it is configured.

+## Swapped Pins
+
+If you have one of the PCB variant with swapped letters `Q` and `B` / `P` and `N`, add the following code to your keymap's `config.h` to swap pins `E6` and `D7` in the firmware:
+```c
+#undef DIRECT_PINS
+#define DIRECT_PINS { \
+    { D7, F7, F6, F5, F4 }, \
+    { B1, B3, B2, B6, D3 }, \
