The [`karlkb.yaml`](./karlkb.yaml) file is used as input.\nThe generated PCB layout is then routed with KiCad (6 and above).\n\nTo generate the PCB files with Ergogen, do\n\n```sh\ncd ergogen\nnpm install\nnode src/cli.js ../karlkb.yaml\n```\n\nYou should now see and `output` folder, which contains a KiCad PCB. Route this PCB and send it off to be manufactured.\n\n## Software\n\nThis keyboard uses ZMK as its firmware. See my [zmk-config](https://github.com/riesinger/zmk-config) repository for the corresponding configuration.\n\n## Thanks to\n\n- [Ben Vallack](https://github.com/benvallack) for exposing me to Ergogen (even though his tutorial is not really comprehensive 😉)\n- [The Ergogen devs](https://github.com/ergogen/ergogen/graphs/contributors). Without them, these keys would never have been straight!\n- [The ZMK devs](https://github.com/zmkfirmware/zmk/graphs/contributors) for providing an awesome and customizable wireless firmware\n- [Josef Adamčík](https://github.com/josefadamcik) for my first ever wireless split keyboard, the [Sofle](https://github.com/josefadamcik/SofleKeyboard)\n- [Anarion](https://github.com/anarion80) for the [Porcupine](https://github.com/anarion80/porcupine) keyboard. This is basically what tought me to use Ergogen. This keyboard is also using his fork with added footprints.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Friesinger%2Fkarlkb","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Friesinger%2Fkarlkb","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Friesinger%2Fkarlkb/lists"}
