I heard that if you go to work and don't know C, you'll get scolded if you don't know Git, but I couldn't find a lecture on YouTube that systematically explains everything from beginning to end. So I searched for this person and listened to it, but my knowledge about Git was disorganized and complicated, but after listening to this lecture, I feel like I've organized Git. I think I learned a lot and saved a lot of time compared to buying a book and studying it. Thank you.
