At this point, make sure that you add your Concrete CMS site to some sort of version control. At PortlandLabs we use both GitHub and Bitbucket for different purposes. They’re both good vendors; highly recommended.
In fact, I believe in version control so strongly that I’m adding this project website to GitHub right now. You’ll be able to follow along with the project of this book throughout various commits. See the progress of the website as it comes together!
