On PHPMaster.com there's a new tutorial introducing you to Zend Framework v2:
When I started writing for PHPMaster, my first article was about Zend Framework. Since then, the framework has released version 2 stable. Apart from the name, version 2 is really a new project compared to the older version; ZF has been totally rewritten. In this article I’ll give you an overview of the new features and the changes that have been introduced.
The article talks about introductory things like getting the framework installed (via a few methods, like Composer) and how the autoloader works with the file/namespace structure. They also talk about the dependencies that come with the framework and the event manager, one of the most powerful parts of the framework.
