How do I use "drush qd"? In Drupal 7, I use drush qd -y and php -S localhost:8000 almost weekly to get a fresh development copy of Drupal 7 to build modules or test modules before I put them into our actual development boxes. 

I'm looking at Drupal 8 without much prior knowledge. Can I still use drush qd as I do with in Drupal 7?
drush qd still works fine with Drupal 8, provided that you are using the 8.x or master branch of Drush. In fact, I just used the latest Drush to download, install and open Drupal 8.1.1, and it worked like a charm.
