On the Zend Framework blog they're asking for your help with the project's documentation. They're looking to the users and community members around the framework to help them make the documentation more useful and stay up to date.

A piece of software is only as good as its documentation. The Zend Framework team and a dozen or so contributors are working hard to improve the Zend Framework 2 documentation, but we still want you to help us improve it even more. Any kind of help is welcome and greatly appreciated.

Most of what they're looking for is clarity - they want to ensure that what's in the manual makes sense (and is correct for the release it relates to). They're also looking for feedback on what helps you learn best - tutorials, user guides, API docs, etc. Issues and suggestions should be posted to the issue tracker in github. If you're not sure where to start, check out the contributors guide.
