Is there a good guide how to use git with kicad? Right now I just copy folders with version numbers. Using it in github sounds like a neat way. Which files should be in my gitignore?
KiBot [0] is super handy for this, the documentation has an explicit section on CI/CD usage.
It does have to basically script drive the GUI to achieve some functionality which has now been added to the kicad cli, so hopefully going forward CI/CD with KiCad will be even easier!
