This is an opinionated cookiecutter template that will set up a directory structure for hardware projects. This is not just PCB (see below), but also all the documentation, and space for firmware, etc.
To use it, you can just use it from the command line directly from GitHub like this:
$ cookiecutter gh:rebma-io/hw-project-cookiecutter
Please feel free to fork this and adapt it to whatever it is you want as your default.
There is a separate cookiecutter template for creating individual PCB
projects. You can use it under the hardware/pcb directly by executing:
$ cookiecutter gh:rebma-io/kicad-cookiecutter
