At work, we are getting ready to start using Git for some code tracking and since I've never used Git before, I thought this would be a great reference to have around at work. It's good timing because I have been interested in trying things out at home on some other projects I have been tinkering with.
The first chapter does a good job in getting you acclimated to some of the basic terminology. I used SVN for a short while on a project and only learned the bare minimum to update my repository and check in a few edits I made for a project so this chapter was useful in getting me going.
The 8 or 9 chapters or so really just goes over the basics you need to know for using a Git as a way to track your coding changes and it has been very useful. It's basic enough that it gets you going.
The last few chapters I haven't really delved into as much but I can see them being useful for those that need it. I'm not at that point yet but I can assume it's good.
Then the final chapter is like a FAQ and is nice.
I would recommend this to anyone that is new to Git like I am.
