Remember you have to flash both halves of the keyboard for it to work!

Make example for this keyboard (after setting up your build environment):

make junco:default

Flashing example for this keyboard:

# For flashing the left half...
make junco:default:uf2-split-left
# or the qmk cli equivalent:

# For flashing the right half...
make junco:default:uf2-split-right
# or the qmk cli equivalent:
qmk flash -kb junco --keymap default -bl uf2-split-right

Bootloader

Enter the bootloader in 3 ways:

Bootmagic reset (works after you have flashed once): Hold down the top far corner key while plugging in the keyboard (~ left half, - right half). This will also clear the EEPROM.
Physical reset button: Hold the BOOT button on the Pico and press the RST button on the Pico, release the the RST button before the BOOT button.
Keycode in layout: In the default layout, the Bootloader keycode is above home row pinky on the right side's adjust layer.

Once you enter the bootloader, the keyboard will show up as a USB device on your computer, you could drag and drop a firmware file to flash it, but I recommend using the flash commands for the respective side.
