I can empathize, been in a similar situation myself. Most of the git tutorials out there have a problem that they don't explain much of the 'why' and just tell about the 'how'. They are telling mostly about commands and not about the concepts behind it.
Some guy at Harvard wrote a great tutorial[1] on understanding git conceptually. It has been on of the best git tutorials I have read myself.
