 This this project demonstrates what is known as a "site-wide" Drush extension. Site-wide extensions are installed via Composer into a particular Drupal site. The other kinds of Drush extensions are Drush module commands and Drush global commands. See the [Creating Custom Drush Commands documentation](http://docs.drush.org/en/master/commands/) for more information.
