In this chapter, we'll worry about adding version control and deploying our applications because when it comes to creating real-world Node apps, deploying your app to the Web is obviously a pretty big part of that. Now in the real world, every single company uses some form of version control. It is essential to the software development process, and most of them aren't using Git. Git has become really popular, dominating the market share for version control. Git is also free and open source, and there is a ton of great educational material. They have a book on how to learn Git. It's free and Stack Overflow is filled with Git-specific questions and answers.
We'll be using Git to save our project. We'll also be using it to back up our work to a service called GitHub, and finally we'll be using Git to deploy our project live...
