Panels 3 Documentation
Last modified: September 14, 2009 - 01:54
Panels 3 is the most recent version of Panels, and is a significant advance over Panels 2, although its user interface is similar in many aspects. Panels 3 is not yet documented in detail, but much of the Panels 2 documentation (except for the API details) should still apply.
Panels 2 for Drupal 6 is deprecated. See Upgrading from Panels 2 to Panels 3 if you are currently using Panels 2 on Drupal 6.

Some docs
I've written a few things. I had planned to turn them into actual d.o docs but haven't had time. I'll link to them for now:

I'm looking for folks to help me out by posting in my Coulee Region forums. You don't need to live in the area; there's plenty of general forums. But please, no Drupal support questions. :)
