1. About Ubuntu
Thank you for your interest in Ubuntu 6.06 LTS - the Dapper Drake release.
Ubuntu is an entirely open source operating system built around the Linux kernel.
The Ubuntu community is built around the ideals enshrined in the Ubuntu Philosophy
[http://www.ubuntu.com/ubuntu/philosophy]: that software should be available free of
charge, that software tools should be usable by people in their local language and despite
any disabilities, and that people should have the freedom to customize and alter their
software in whatever way they see fit. For those reasons:
ã Ubuntu will always be free of charge, and there is no extra fee for the enterprise
edition, we make our very best work available to everyone on the same Free terms.
ã Ubuntu includes the very best in translations and accessibility infrastructure that the free
software community has to offer, to make Ubuntu usable for as many people as possible.
ã Ubuntu is released regularly and predictably; a new release is made every six months.
You can use the current stable release or the current development release. Each release is
supported for at least 18 months.
ã Ubuntu is entirely committed to the principles of open source software development; we
encourage people to use open source software, improve it and pass it on.
The Ubuntu community is comprised of developers, programmers, testers, techwriters,
documentation testers, translators, and most importantly, the people who use Ubuntu every
day. We invite you to join this community and help make Ubuntu the operating system
you, your family, your friends, and your colleagues will love to use. Help us translate
Ubuntu into your language, try it on new and unusual hardware, improve the experience of
other users with hints, tips, and FAQs, or help to shape the direction Ubuntu is headed by
providing feedback about the software you love most.
