FIRST have a look at our site: http://ubuntu-manual.org

Designed to be as user-friendly and easy to follow as possible, it should provide the first point of reference to any Ubuntu newcomer with lots of information in one easy to access PDF file. Plus, every six months there will be a new revision released to coincide with each new release of Ubuntu.

Contributions of any kind are welcome. To see how to contribute, go here: http://ubuntu-manual.org/getinvolved
