While taking the vue.js lecture, I had no choice but to learn about git... So I signed up for the lecture and came in. It was very helpful. I installed git on my laptop at home and practiced while keying in the video lecture, and I understood a lot. Of course, I haven't used git in practice yet, so I can't feel its weight and problems in real situations, but it was a very good lecture to understand what git is. Thank you very much. The end.
