-==== Flashing bootloader using Arduino UNO or Arduino MEGA====
+===== Flashing bootloader using USB Programmer =====
+The simplest process.
+  - Connect programmer to computer
+  - Connect programmer to motherboard
+  - Open Arduino IDE
+  - Select the programmer you use in the Tools -> Programmer menu
+  - Choose "Burn Bootloader" in the tools menu
+  - Go back to normal life, flashing via USB cable direct to your 3D printer.
+===== PLAN A: Flashing bootloader using Arduino UNO or Arduino MEGA - Method 1 ====
+Don't have a USB programmer lying around? Feeling like you would like to buy an arduino for future projects anyway?
+Read on...
+**You can use an Arduino as a USB programmer fairly easily!**
+Download and flash [[https://www.gammon.com.au/bootloader|this awesome arduino bootloader flasher by Nick Gammon]].
+All your pins on the MKS Gen L should be connected to the ICSP port (see first image below).
+  - Connect pin 10 on the uno to the RST on the MKS Gen L ICSP port (see image #2 for pinout)
+  - Connect MISO, MOSI, SCK, VCC, GND to the matching pins on both MKS ICSP and uno ICSP headers.
+  - Flash the bootloader sketch.
+  - Open the arduino serial monitor.
+  - You may need to choose the correct baud rate to see text correctly.
+  - Follow the prompts in the serial monitor.
