I agree with the "learn the CLI", but to newcomers I'll also suggest to look at the IDE/editor's output channel - if there's GUI for Git, there are also most likely logs for what's happening under the hood - even if a little noisy, it can be a good learning resource. And of course if you're learning and unsure of what's happening (with the CLI or through a GUI), do so in a non-destructive manner (by having proper backups).
