+## 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 ferris/sweep:default:avrdude-split-left
     make ferris/sweep:default:avrdude-split-right
 
-Subsequent make example for both sides:
+[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
 
-    make ferris/sweep:default
+## Bootloader
 
-[Bootmagic lite](https://docs.qmk.fm/#/feature_bootmagic?id=bootmagic-lite) is also configured on the top right key for the right halve.
+Enter the bootloader in 3 ways:
+
+* **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.
