Have you ever lost hours of work because you accidentally deleted a file or forgot to save it?
Or maybe you wanted to go back to a previous version of a file but couldn't, because the history of changes was not saved?
These are the problems that version control systems solve.
They allow you to save the history of changes and go back to any previous version of a file. On top of that they allow you to share the history of changes with other people.
Git is the defacto standard for version control. It is used in almost every software project. If you are a software developer, you need to know Git.
The goal of this book is to get you up and running using Git from the command line as quickly as possible without overwhelming you with too much information.
To make the learning process more intuitive and engaging, I use mental models, analogies and metaphors to help you understand and remember the concepts.
