As you probably know, we're working on creating a User Guide for Drupal 8. We started working on the actual content about two weeks ago, and several topics are in progress. We started writing before we were really sure what the guide should contain, working on a short list of topics we were pretty sure we'd want to include.
So I'm pleased to announce that today we just posted a complete outline of topics for the guide -- it should be pretty much complete now, although we may realize we need a new topic or two, or that a topic or two could/should be removed. You can see the full outline at:
https://userguide-drupal.redesign.devdrupal.org/d8guide/en/index.html
Note that some of the topics marked UNWRITTEN are being worked on -- they just haven't been fully written yet.
If you want to pick a topic and write (or edit), the guide to how to do this is at:
https://www.drupal.org/project/user_guide
under Get Involved. I will also be updating some of the instructions in the next few days for better clarity (hopefully).
Hope to see you writing or editing soon!
