In this tutorial you'll learn how to access and use each Pantheon environment. We'll start by assuming we have done a bunch of work in our initial Dev environment and we're ready to create the Test and Live environments. Once we have all three environments up and running, we'll make some changes to our site code in Dev. With that done we'll merge the code changes in Dev with the Live database in Test so we can make sure everything looks good. We'll also run a site check on Test. Once everything looks clear, we'll deploy the code changes to the Live environment. After deployment we'll see how to pull the Live database back down to our Dev environment whenever we need to.
You can access your code using either SFTP or Git. In this tutorial we'll be using Git. If you'd like to learn more about Git, or get a refresher, you can watch our Introduction to Git Series.
