A brief introduction about Ubuntu-Manual.org:
Our project is an open source volunteer effort to create and maintain quality documentation for Ubuntu and its derivatives.So, what's in Getting Started with Ubuntu 12.10 book? This book is suitable for those who are new in Ubuntu.
We were founded in 2009 by Benjamin Humphrey, who saw the need for targeted up-to-date and consistent documentation for the Ubuntu operating system.
It didn’t take long until the project amassed hundreds of contributors, and what Benjamin originally envisioned became a reality as the Ubuntu Manual Project blossomed into an ambitious and successful project. We have a strong emphasis on just "getting things done" and therefore we have a fast-paced development environment filled with lots of unique ideas.
Our mission is to provide a wide range of quality educational materials to lower the Linux barrier to entry for new users and in turn increase Ubuntu’s market share.
