This layout is for those who prefer defining their layout in a keymap.c, instead of graphically with a keymap.json. It is the same as the default keymap.json layout, except for having only a QWERTY base layer.
The make and flash commands are
make hillside/52:default_dot_c
make hillside/52:default_doc_c:flash
It also serves as a simple, clean layout to verify that the configuration and switches work. Use the QMK Configurator Tester to see that the switches produce output. All the keys should register on the layout tester except for the caps word and the two layer keys. The LEDs should glow a nice red. If they do not, you may need to clear the persistent EEPROM settings with the EE_CLR key on the adjust layer, or enable them with the RGB_TOG key.
