MIT's course speaks too fast, a paid course I took was too slow and dragging, and I couldn't get through Git's official documentation; I eventually discoveredLiao Xuefeng's Git tutorialsuits me quite well.
If you're following Liao Xuefeng's tutorial, note: 1. Go to your GitHub homepage, click the avatar at the top right, click Settings, click Repositories on the left, and change the Repositories default branch name from master to main
2. In VS Code, use Ctrl+` to open the terminal and Ctrl+J to close it; you can enter git commands in the terminal or use the Git extension inside VS Code
