Existing ‘Understanding Drupal’ guide got migrated into new documentation system as ‘Understanding Drupal‘ for Drupal 7.
We need to create similar guide for Drupal 8. The guide itself exists: https://www.drupal.org/docs/8/understanding-drupal, but it is empty.
– Sign up as a maintainer for D8 Understanding Drupal guide
– Review D7 Understanding Drupal guide content and copy information that is relevant for D8 into D8 guide
– Add D8 specific information to the new guide
