+## Make the QMK DFU .hex
+`make lets_split/rev2:wanleg:production dfu=qmk` 
+
+## Burning EEPROM settings and Firmware
+Navigate to the directory with your .hex file and the `eeprom-lefthand.eep` and `eeprom-righthand.eep` files in it.  
+**Burn Left Side With QMK DFU and Firmware**  
+`avrdude -b 19200 -c avrisp -p m32u4 -v -e -U lock:w:0x3F:m -U efuse:w:0xC3:m -U hfuse:w:0xD9:m -U lfuse:w:0x5E:m -U eeprom:w:eeprom-lefthand.eep -P comPORT -U flash:w:YOUR_production.hex:a`  
+
+**Burn Right Side With QMK DFU and Firmware**  
+`avrdude -b 19200 -c avrisp -p m32u4 -v -e -U lock:w:0x3F:m -U efuse:w:0xC3:m -U hfuse:w:0xD9:m -U lfuse:w:0x5E:m -U eeprom:w:eeprom-righthand.eep -P comPORT -U flash:w:YOUR_production.hex:a`  
+
+Change `comPORT` to whatever port is used by the Arduino (e.g. `com11` in Windows or `/dev/ttyACM0` in Linux). Use Device Manager in Windows to find the port being used. Use `ls /dev/tty*` in Linux. Change `YOUR_production.hex` to whatever you've created in the previous step.
+
+## Using QMK DFU  
+Once QMK DFU is burned to your ProMicro, you can then flash subsequent hex files with
+`make lets_split/rev2:<keymap>:dfu dfu=qmk`  
+The `dfu=qmk` conditional will set `BOOTLOADER = qmk-dfu` instead of `BOOTLOADER = caterina`
