hellen-one is a toolset to produce custom PCBs by merging gerber files of known proven functional modules into trivial _frame_ PCB with mostly just the main vehicle connector. Gerber merging happens in the cloud, i.e. on the github server.
* fork https://github.com/rusefi/hellen-example/ repo to get github actions and meta files [learn about forking](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo)
* push into github to trigger hellen-one gerber expert and gerber merge (that's where the hellen magic happens! for instance gerber export is taken care by [export.sh](https://github.com/andreika-git/hellen-one/blob/master/kicad/bin/export.sh) script which github action would invoke _automatically_. Just watch for the yellow circle to turn into a green checkmark.)
