Wow! We covered a lot in this first chapter. You should now be able to install Docker on your workstation, regardless of the OS that it is running. You should be able to install Docker onto a Linux workstation using three different methods, and know some of the differences between installing on an RPM-based system and a DEB-based system. 

We also covered some very significant reasons why you might consider using a Linux workstation for your development, instead of using a Windows or macOS workstation. And by now, you should be able to easily validate the successful installation of Docker by checking the version of Docker installed. 

You should be able to easily confirm that Docker is working as desired by running a hello-world container. Not bad for your first chapter, right? Well, with this foundation, and your newly Docker-ready workstation, let's move right into Chapter 2, Learning Docker Commands, where we will learn about many Docker commands you'll use every day.
