You probably have a great deal of understanding and knowledge about Git, and this book might be a good resource.
I'm not asking you to do anything differently, and yet I think it's important to realize that people have a deep aversion to text that appears to be LLM generated.
By "shame", I meant that just from a skim of the contents of this book, it can be hard to distinguish it from any other LLM generated text by any other author who has no idea what they're talking about.
That makes people (like me) inclined to discount what it has to say, potentially losing out on good technical content.
An interesting point to consider: an author that goes out of their way to hide any LLM influence may actually be degrading the signal. Because in that case, you'll not see the LLM's etchings, and misattribute skill to the author under the belief an LLM was not involved. Complicated times.
