We're happy to finally have the site done! We've been doing a lot of documentation and guides over the past month. If you're new to php-activerecord or just interested in finding out what it's about, head over to the quick start guide. We've got many other guides as well in addition to the api documentation.
Look for the 1.0 release sometime in the next few months. It should have new stuff like additional database adapters and other cool things.
If you have any questions and/or feedback please don't hesitate to contact us.
