Managing, storing, and moving the configuration is a critical need for almost any site. We started with learning the intricacies of the configuration files and schemas and how to create our own. From there, we looked at how to load and store our own configuration and override it for particular environments.
Next, we worked on exporting and importing a configuration. We went through how to do that through the web interface, as well as through Drush. Finally, we learned how to use the configuration system on a multilingual site.
In the next chapter, you will be learning how to migrate a site from an earlier version of Drupal to Drupal 8. We will be using the migration steps built into Drupal 8 core and then customizing the process with your own custom code.
