Announcing www.d8cards.com - A simple Drupal 8 ladder for small study groups
At my workplace, we had earlier formed a study group to try out some very simple Drupal 8 stuff.
As we progressed, we had built a bunch of activity cards that we used for the group.
They are now available @ www.d8cards.com.
Check them out. Each activity card has a tutorial and an exercise that you could try out. There are 21 cards covering varied Drupal 8 Topics.
