Thank you, but the requested book is about how the Git codebase works.
Quote from the book description on Amazon:
In "Decoding Git," you’ll dive deep into Git's original C code to learn what makes Git tick. You will begin with an introduction to Git's code and an overview of its original version. You will then learn how to install Git's original version and the essential commands you need to know to work with Git. You will then examine each of Git's core components, including the C code files: cache.h, read-cache.c, init-db.c, update-cache.c, write-tree.c, commit-tree.c, read-tree.c, cat-file.c, and show-diff.c
