The Ubuntu-Manual.org is a a great project lead by Benjamin Humphrey. It is another excellent answer to the “where’s the manual?” question similar to what we have been doing with our two pamphlets designed to introduce users to Linux and as an overview of first steps after a first installation.
Documentation for new Linux users is an important element to help users transition from other operating systems. Since users start with different background, there is difficulty in providing concise yet complete documentation for different types of users. People need to become feel comfortable and effective using their computers. While there are many past efforts that have tried to provide good documentation for new Linux users no single guide has taken hold and become whidespread yet.
It is a pretty impressive document. Glad this hole is finally being filled.
