In this chapter, we have installed our CI environment. We have discussed the various tools we are going to use throughout the book. We have also had our first look at Git, Jenkins, and SonarQube and made them work together. In the remainder of the book, we are going to install many more tools on the server and locally. But before we get to that, we will take a closer look at Git in the next chapter, as there is a lot more to Git than we have seen so far.
