Hey, Pascal here, the author.

I understand this reaction. And just like you've pointed out, it's actually not a whole" book about a single command.

In order to get a good understanding of rebasing, I believe it's good to have a solid foundation of how git works, which is pretty much what the first half of the book covers.

I could've left that out and only talk about rebasing without going into all the other topics but then, for someone who isn't experienced with the internals of git will have a hard time following what's going on.
