-1. While plugging in the USB cable, hold the two right-most keys on the left half of the ErgoDone to enter FLASH mode.
-2. Use the `hid_bootloader_cli` utlity from [TKG Toolkit](https://github.com/kairyu/tkg-toolkit):
-
- hid_bootloader_cli -mmcu=atmega32u4 ergodox_ergodone_default
+# Flashing the firmware onto the keyboard
+
+The ErgoDone uses a customized HID bootloader rather than the Teensy one. It doesn't need an OS driver, and the required actions before flashing are a little different than with an ErgoDox.
+
+1. To enter flash mode, disconnect the keyboard first. Then, on the left-hand device, in the top row, press and hold the two rightmost keys while reconnecting the keyboard.

+2. To flash the .hex file, use the `hid_bootloader_cli` utlity from the [TKG Toolkit](https://github.com/kairyu/tkg-toolkit) (as of 2017-10-03, only [this old version](https://github.com/kairyu/tkg-toolkit/blob/b14c67ca8bc84c07e5fc6b2e01ae4002b808243a/windows/bin/hid_bootloader_cli.exe) works under Windows):
+
+ hid_bootloader_cli -mmcu=atmega32u4 ergodone_default.hex
