+## Setting Handedness
+
+Keyboard uses [handedness by EEPROM](https://docs.qmk.fm/#/feature_split_keyboard?id=handedness-by-eeprom) as default. The make commands are:
+
+    make a_dux:default:dfu-split-left
+    make a_dux:default:dfu-split-right
+
+[QMK Toolbox](http://qmk.fm/toolbox) can also be used to set EEPROM handedness. Place the controller in bootloader mode and select menu option Tools -> EEPROM -> Set Left/Right Hand
 
 ## Bootloader
 
 Enter the bootloader in 3 ways:
 
-* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard. (With `EE_HANDS` configured, hold down the top right key on the right half to place the right controller in bootloader mode)
-* **Physical reset**: Briefly short the RST and GND pins on the microcontroller using tweezers, a paperclip, or any other conductive material.
-* **Keycode in layout**: Press the key mapped to `RESET` if it is available
