This book basically explains the basic operation of version management.The most important thing is that each operation will tell you what the principle of the operation is.The most important thing in books is to teach them how to fish. Of course, some people may not be very accustomed to it, and may feel a bit disorderly.Personally, I think this is the wrong way.I recommend browsing the full text first, and then operating on the computer.Add your own ideas and verify according to the verification method given later.Get twice the result with half the effort, even draw inferences from one instance. Of course, this book has some shortcomings. The data is not systematic. I think since it is a guide, it is better to give all the parameters of this command in a certain part.The following appendix is also a complete list of commands. Generally speaking, it is a rare good book.Through this book, I decided to give up svn completely..Git is a good thing
