*Composer Beginners, that is ;-)
In this session, you'll learn the basic basics of using composer to manage a Drupal 8 site. There's a steep learning curve for most Drupal site builders who try to start using composer with their Drupal 8 sites, so hopefully this session will at least help you get you off the ground.
I'll be showing things from an Ubuntu machine, which should be close enough for Mac users, but I won't be doing anything in Windows. #sorrynotsorry
