I'm still relatively new to git / Github and struggling with the following:
I have a repo with the branch main. I've created a couple of new branches that are based on main. I want to be working on these new branches individually, but sometimes I would like to change some 'core features' and change the main branch, and eventually also see these changes on the other branches.
I'm not sure how to do this. I've already created the repo and branches (also remote), but if I change the main branch then I don't know how to reflect those changes on the other branches.
