As we progress through each lesson of Mastering Drupal 8, it is important that a local development environment has been set up with the basic tools we covered in this lesson. That includes an instance of Drupal 8 with Composer, Drush, and Drupal Console. By now, it should also be clear how each tool can expedite tasks that would manually take a lot longer to perform. These tools should be part of every Drupal project as they will help you master your skills as a developer.
In the next chapter, we will begin to walk through Drupal 8 site configuration, including changes to the administrative interface, how to manage regional settings, site information, and performance while developing.
