Phew! This was our first chapter where we actually got into some code. As you saw, first we were able to check that our server can actually run Doctrine.

Lastly we learned how to implement Doctrine by setting up a small test environment that we will use to perform some exercises in the remaining chapters of the book.
Now lets move on and get our first taste of Doctrine connections in the Introduction to Connections chapter.
