\marginnote{For information on Ubuntu Server Edition, and how you can use it in your company, visit \url{http://www.ubuntu.com/business/server/overview}.} While large organizations often find it useful to pay for support services, \Index[Shuttleworth, Mark]{Shuttleworth} has promised that the Ubuntu desktop system will always be free. As of 2010, Ubuntu is installed on nearly 2\% of the world's computers. This equates to millions of users worldwide, and is growing each year.

The Linux \Index{kernel} is the shift manager of the operating system; it is responsible for allocating memory and processor time. It can also be thought of as the program which manages any and all applications on the computer itself.

\marginnote{While modern graphical \glspl{desktop environment} have generally replaced early command-line interfaces, the command line can still be a quick and efficient way of performing many tasks. See \chaplink{ch:advanced-topics} for more information, and \chaplink{ch:the-ubuntu-desktop} to learn more about \gls{GNOME} and other desktop environments.} Linux was designed from the ground up with security and hardware compatibility in mind, and is currently one of the most popular \Index{Unix}-based operating systems. One of the benefits of Linux is that it is incredibly flexible and can be configured to run on almost any device\dash from the smallest micro-computers and cellphones to larger super-computers. \Index{Unix} was entirely command line--based until graphical user interfaces (\glspl{GUI}) began to emerge in the early 1990s.

\textbf{Ubuntu is community based.} That is, Ubuntu is developed, writen, and maintained by the community. Because of this, support is probably not available at your local computer store. Fortunately, the Ubuntu community is here to help. There are many articles, guides, and manuals available, as well as users on various Internet forums and Internet Relay Chat (\acronym{IRC}) rooms that are willing to assist beginners. Additionally, near the end of this guide, we include a troubleshooting chapter: \chaplink{ch:troubleshooting}.

\textbf{Many applications designed for Microsoft Windows or Mac \acronym{OS~X} will not run on Ubuntu.} For the vast majority of everyday computing tasks, you will find suitable alternative applications available in Ubuntu. However, many professional applications (such as the Adobe Creative Suite) are not developed to work with Ubuntu. \marginnote{To learn more about \gls{dual-booting} (running Ubuntu side-by-side with another operating system), see \chaplink{ch:installation}. For more information on Wine, go to \url{http://www.winehq.org/}.} If you rely on commercial software that is not compatible with Ubuntu, yet still want to give Ubuntu a try, you may want to consider \gls{dual-booting}. Alternatively, some applications developed for Windows will work in Ubuntu with a program called \application{Wine}.

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. The Ubuntu Manual Team emphasizes ``getting things done,'' and therefore operates in a fast-paced development environment filled with lots of unique ideas.

\marginnote{Many companies (such as \Index{Dell} and \Index{System76}) sell computers with Ubuntu preinstalled. If you already have Ubuntu installed on your computer, feel free to skip to \chaplink{ch:the-ubuntu-desktop}.} Before you can get started with Ubuntu, you will need to obtain a copy of the Ubuntu installation image for \acronym{CD} or \acronym{USB}. Some options for doing this are outlined below.

\marginnote{The majority of computers in use today will meet the requirements listed here; however, refer to your computer's documentation or contact the manufacturer for more information.} Ubuntu runs well on most computer systems. If you are unsure whether it will work on your computer, the Live \acronym{CD} is a great way to test things out first. Below is a list of hardware specifications that your computer should meet as a minimum requirement.
