This may not be quite the right forum to post this question, but since it's the only one pertaining directly to Ext JS 4, I thought it would be best.

I can't seem to find a "Getting Started Guide" for the 4.0 release. I'm sure this is due to the "Developer Preview", but I've never worked with Ext JS before, so any help would be appreciated.

Anybody have a "quickstart" guide for 4.0? I've heard that there is new a build process in place, and I want to make sure I start using it from the beginning.
