After having installed KMK on the previous page, you're going to want to click 'Download Project Bundle' on the file below. Unzip the file, copy kb.py to your CIRCUITPY drive and rename main.py to code.py and copy it to the CIRCUITPY drive as well.

from kmk.kmk_keyboard import KMKKeyboard as _KMKKeyboard

class KMKKeyboard(_KMKKeyboard):
led = digitalio.DigitalInOut(board.D9)
led.direction = digitalio.Direction.OUTPUT

After you've copied everything over, your CIRCUITPY drive should look something like this.
There are 3 different keymaps available in the files. The default one is just the nav cluster, which is the four arrow keys and the 6 nav keys. There is also a keymap designed to give you a few keys to navigate i3 quicker (you'll probably have to edit this one since I use COLEMAK as well). The third keymap is for media control.
If you want to have a specific one be the main one, move it to the top of the keyboard.keymap list in code.py. For example, if I wanted to have the media keys be active, I would edit code.py to look like this:
At this point, the keyboard should just work when you hit the keys. Feel free to mess around with the key maps. KMK has some good documentation on this process.
