Using Ubuntu Linux/Introduction for Ubuntu users
Welcome all Ubuntu users. You're probably already familiar with what Ubuntu is and how it differs from other operating systems, so we won't go into that. Instead allow me to welcome you to the Ubuntu Wikibook. Please feel free to (in the spirit of Ubuntu) help out in the making of this Wikibook wherever you feel you can.
We hope that new Ubuntu users and veterans alike will be able to learn something from this guide.
