With git/github I really only pull and push. I don't really use any of the other features. Same for the kids on my robotics team. The only thing I have taught them is pull and push. The kids do a pull at the beginning of practice and a push at the end. Yet sometimes I see this in the commit logs. Why are these merges happening? Even I have some merges and I know I didn't do anything differently. Should I be concerned? We are doing all of our git/gihub work in VS code if that matters.
