Say I'm working on the ADC, first I'll make a git branch for my work...
Say I'm working on the ADC, first I'll make a git branch for my work...
then I'll do work in the adc.kicad_sch file, and when I'm ready to submit the updated schematic I'll upload it to my schematic branch.
This way I can push/pull changes to the adc schematic separately, so I can safely work on the adc schematic without the need to resolve merge conflicts.
You are free to create and manage your footprint and symbol libraries locally in any way you choose--try to be organized because it will help us create a shared symbol library.
