This repository contains the board definitions for the nightliner mechanical, split keyboard. Since these are two boards with an MCU directly on the PCB, there are no shield definitions, just two boards. They live under the config/boards/arm/nightliner path.
The firmware can be built locally, if all of ZMK's and Zephyr's toolchain are installed using the command lines:
west build -p -d build/left -b nightliner_left -- -DZMK_CONFIG="${HOME}/Software/keyboard/zmk-config/config"
west build -p -d build/right -b nightliner_right -- -DZMK_CONFIG="${HOME}/Software/keyboard/zmk-config/config"
But also as designed by the good people from the ZMK project, a github workflow is triggered on every push that changes the firmware relevant files.
The board directory also contains my default keymap definition. The graphical representation below is directly generated from the keymap file using Cem Aksoylar's excellent keymap-drawer tool.
The images are also autogenerated using github workflows.
The keymap is currently very simple, will probably evolve over time, once I get the keyboard fully up and running. Here is a representation of it: 
For some configuration aspects it is important to know, what the exact sequential number of each key is. I used the keymap-layout-tools helper app from Nick Coutsos. The keypositions representation is here:
