There are two more days left in the WordPress Codex Cleanup. You can read all about it, or just come volunteer.
Many new articles have been posted, too. Check them out.
You can also reach us on the IRC Chat FreeNode on the #wordpress-docs channel to walk you through the process or toss around ideas.
Thousands of edits have happened in the last week, and YOUR resource for documentation and instructions on using WordPress is being cleaned up by a great crew of volunteers, but we still need your help.
