This is a place for QML tutorials (more like cookbook recipes) I'm (User:Elliot) writing as I learn QML.
My approach to learning a language is to attempt to build a realistic application, with all the trappings that entails. I'm doing the same thing while learning QML.
There is plenty of documentation for QML/Qt Quick: see http://doc.qt.nokia.com/4.7/qtquick.html, for example. But there is little of it which is specific to MeeGo. And the "developer story" is there, but not documented thoroughly (it probably will be shortly).
Eventually they should probably go into a /QML/ namespace.
You're probably going to want to look at the QML elements documentation while you go through these recipes. You can find it at http://doc.qt.nokia.com/4.7/qdeclarativeelements.html.
http://doc.qt.nokia.com/4.7/ might come in useful, too, if you want to learn more about Qt and go through the official tutorials.
