I am reporting https://www.drupal.org/documentation/structure → to moderators because it contains confusing and outdated terminology. The primary issue is lack of mention of entities, and a misleading emphasis on content types (and even panels, not a core concept). This page is one of the most logical jumping off points for on drupal.org for discussions of how information is structured in Drupal. I'd be happy to take a pass at improving it and helping it better reflect what's in Drupal 8.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
