So far I've found this (via google search, not from a link on your site):
I've also found the Scribd Pagelines 2 doc, but it seems to be a basic guide.
Is the doc.pagelines.com information up-to-date?
It seems to have more detail, but it's unclear if it's up-to-date info. I'd suggest dating the documentation so people know what's current. Is there a PDF version of this documentation? I'd like to be able to download, read offline and search it too like the Scribd doc.
Lastly, in my opinion the DOCS should be available using via the SUPPORT area in your nav menu on the main site.
