# This is a puppet function similar to the hiera() lookup function.
#
# It can load yaml, json or ruby config files

# 
# You could also use ruby any way you like inside these configuration files, including calling out

Create a keyboard layout and download a firmware https://input.club/configurator-ergodox/

Unzip the firmware archive and have the .kll files ready

Create a logo, save it as a black on white 128x32 .bmp
