This brings us to the end of our journey in to the world of Ruby. We have looked at variables, operators, statements, and methods, and eventually had a sneak peek into the world of OOPs. We have learned about classes, objects, and modules. We'll make use of most of the stuff we learned here throughout this book. We'll be extending our knowledge of Ruby as and when we move on to structures involving JSON objects and so on.

In the next chapter, we'll cover concepts such as organizations, groups, and users, and how you can allow for fine-grained access to different types of objects on the Chef server.
