Our goal is to cover the basics of Ubuntu (such as installation and working with the desktop) as well as guide you through some of the most popular applications. We designed this guide to be simple to follow with step-by-step instructions and plenty of screenshots, allowing you to discover the potential of your new Ubuntu system even if you are a novice computer user or are migrating from another operating system for the first time.

Please bear in mind that this guide is still very much a work in progress and always will be. It is written specifically for Ubuntu 10.04 \acronym{LTS}, and although we have aimed to not limit our instructions to this version it is unavoidable that some things will change over the life of Ubuntu. Whenever a new version of Ubuntu is released, we will incorporate any changes into our guide, and make a new version available at \url{http://www.ubuntu-manual.org}.

\marginnote{More information about Ubuntu's online and system documentation can be found in \chaplink{ch:learning-more}.}

If you are after more detail, there are excellent resources available at \url{http://help.ubuntu.com}. Ubuntu's built-in system documentation is also very useful for accessing help on specific topics, and can be found by clicking \menu{System\then Help and Support} in Ubuntu. If something isn't covered here, chances are you will find the information you are looking for in one of those locations. We will try our best to include links to more detailed help wherever we can.

Ubuntu philosophy

The term ``Ubuntu'' is a traditional African concept that originated from the Bantu languages of southern Africa. It can be described as a way of connecting with others\dash living in a global community where your actions affect all of humanity. Ubuntu is more than just an operating system: it is a community of people that come together voluntarily to collaborate on an international software project that aims to deliver the best possible user experience.

The Ubuntu promise

Ubuntu will always be free of charge, along with its regular enterprise releases and security updates.

Ubuntu comes with full commercial support from \gls{Canonical} and hundreds of companies from across the world.

Ubuntu core applications are all free and open source. We want you to use free and open source software, improve it, and pass it on.

Ubuntu was conceived in 2004 by Mark Shuttleworth, a successful South African entrepreneur, and his company \gls{Canonical}. Shuttleworth recognized the power of Linux and Open Source, but was also aware of weaknesses that prevented mainstream use.

\marginnote{Canonical is the company that provides financial and technical support for Ubuntu. They have employees based around the world who work on developing and improving the operating system, as well as reviewing work submitted by volunteer contributors. To learn more about Canonical, go to \url{http://www.canonical.com}.}

Shuttleworth set out with clear intentions to address these weaknesses and create a system that was easy to use, completely free (see \chaplink{ch:learning-more} for the complete definition of ``free''), and could compete with other mainstream operating systems. With the Debian system as a base, Shuttleworth began to build Ubuntu. Using his own funds at first, installation \acronym{CD}s were pressed and shipped worldwide at no cost to the end user. Ubuntu spread quickly, the size of the community rapidly increased, and it soon became the most popular Debian-based Linux distribution available.

Now with more people working on the project than ever before, Ubuntu continues to see improvement to its core features and hardware support, and has gained the attention of large organizations worldwide. For example, in 2007 Dell began a collaboration with Canonical to sell computers with Ubuntu pre-installed. Additionally, in 2005 the French Police began to transition their entire computer infrastructure to a variant of Ubuntu\dash a process which has reportedly saved them ``millions of Euro'' in licensing fees for Microsoft Windows. By the year 2012, the French Police anticipates that all of their computers will be running Ubuntu. Canonical profits from this arrangement by providing technical support and custom-built software.
