Ask HN: What's the Best Git Book?
2 by chrisshroba | 2 comments on Hacker News.
I'm motivated half by wonder at the scope of what git can do, and half by the frustration of ending up in weird states and struggling with figuring out if I'm supposed to reset, revert, or restore. Any good books for understanding git at a deeper level?
