Summary

In this chapter, we went over how to create new Yii2 applications via composer. We also went over the basic configuration files that come with Yii2 as well as how to configure our web application to load environment-specific configuration files. Finally, we also covered components, objects, and path aliases, which are fundamental to gaining mastery over Yii.
