<chapter id="introduction">
<title>What is Software Center?</title>
<para>
Software Center is a virtual catalog of thousands of free
applications and other software to make your computer more useful.
</para>
<para>
You can find software by category or by searching,
and you can install an item with the click of a button.
</para>
<para>
The Center also lets you examine the software installed on the
computer already,
and remove anything you no longer need.
</para>
</chapter>
<chapter id="installing">
<title>Installing software</title>
<para>
To install something with Software Center,
you need administrator access and a working Internet connection.
(If you set up the operating system on this computer yourself,
you have administrator access automatically.)
</para>
<orderedlist>
<listitem>
<para>
In the <guilabel>Get Software</guilabel> section,
find the thing you want to install.
If you already know its name, try typing the name in the search field.
Or try searching for the type of program you want
(like “spreadsheet”).
Otherwise, browse the list of departments.
</para>
</listitem>
<listitem>
<para>
Select the item in the list, and choose
<guilabel>More Info</guilabel>.
</para>
</listitem>
<listitem>
<para>
Choose <guilabel>Install</guilabel>.
You may need to enter the administrative password
before the installation can begin.
</para>
</listitem>
</orderedlist>
<para>
How long something takes to install depends on how large it is,
and the speed of your computer and Internet connection.
</para>
<para>
When the screen changes to say “Installed”,
the software is ready to use.

<chapter id="launching">
<title id="launching-title"
>Using a program once it’s installed</title>
<para>
Most installed applications appear
in the <guimenu>Applications</guimenu> menu in the corner of the screen,
in the same category as they came from in the Software Center.
</para>
<para>
For example, if you installed a program from the
<guilabel>Office</guilabel> department, it will appear inside
<menuchoice><guimenu>Applications</guimenu>
<guisubmenu>Office</guisubmenu></menuchoice>.
</para>
<para>
Utilities for changing settings may appear inside
<menuchoice><guimenu>System</guimenu>
<guisubmenu>Preferences</guisubmenu></menuchoice> or
<menuchoice><guimenu>System</guimenu>
<guisubmenu>Administration</guisubmenu></menuchoice>.
</para>

<chapter id="removing">
<title id="removing-title">Removing software</title>
<para>
To remove software, you need administrator access.
(If you set up the operating system on this computer yourself,
you have administrator access automatically.)
</para>
<orderedlist>
<listitem>
<para>
In the <guilabel>Installed Software</guilabel> section,
find the item you want to remove.
</para>
</listitem>
<listitem>
<para>
Select the item in the list, and choose <guilabel>Remove</guilabel>.
You may need to enter the administrative password.
</para>
</listitem>
</orderedlist>
<para>
If a program is open when you remove it,
usually it will stay open even after it is removed.
As soon as you close it, it will no longer be available.

>Why is it asking me to remove several programs together?</title>
<para>
Sometimes if you try to remove one item,
the Software Center will warn you that other items will be removed too.
There are two main reasons this happens.
</para>
<itemizedlist>
<listitem>
<para>
If you remove an application, any add-ons or accessories
for that application usually will be removed too.
</para>
</listitem>
<listitem>
<para>
Multiple applications are sometimes provided as a single package.
If any of them are installed, all of them are installed.
And if any of them are removed, all of them are removed.
Software Center cannot remove them individually,
because it has no instructions on how to separate them.
</para>
</listitem>
</itemizedlist>
<para>
You can use the <guilabel>Main Menu</guilabel> settings to hide unwanted
items without removing them from the computer.
In GNOME, you can find <guilabel>Main Menu</guilabel> inside
<menuchoice><guimenu>System</guimenu>
<guisubmenu>Preferences</guisubmenu></menuchoice>.

<chapter id="canonical-maintained">
<title>What is “Canonical-maintained”?</title>
<para>
Some of the software available in Ubuntu Software Center is
maintained by Canonical.
Canonical engineers ensure that security fixes and other critical updates
are provided for these programs.
</para>
<para>
Other software is maintained by the Ubuntu developer community.
Any updates are provided on a best-effort basis.
</para>
</chapter>
<chapter id="canonical-partners">
<title>What is “Canonical Partners”?</title>
<para>
<guilabel>Canonical Partners</guilabel> shows software from vendors who
have worked with Canonical to make their software available for Ubuntu.
</para>
<para>
You can install this software in the same way as any other software in
Ubuntu Software Center.
</para>
</chapter>
-->
<chapter id="why-free">
<title id="why-free-title">Why are all the programs free?</title>
<para>
Currently, all software in Software Center is free of charge.
</para>
<para>
Most of this software is developed as <firstterm>open source</firstterm>,
which means anyone is allowed to alter it and redistribute it for any
price.
Ubuntu developers, Debian developers, and others
package the software available in Software Center,
and make it available to you for free.
</para>
</chapter>
<chapter id="missing">
<title id="missing-title"
>What if a program I want isn’t available?</title>
<para>
First, check that <menuchoice><guimenu>View</guimenu>
<guimenuitem>All Software</guimenuitem></menuchoice> is selected.
</para>
<para>
If the software you want still isn’t there,
but you know that it runs on this operating system,
try contacting the original developers of the program
to ask if they can help make it available.
</para>
<para>
If a program is available for other operating systems but not for this one,
let the developers know that you’re interested in running it on
this operating system.
</para>
</chapter>
<chapter id="bugs">
<title id="bugs-title"
>What if a program doesn’t work?</title>
<para>
With tens of thousands of programs in Software Center,
there’s always the chance that a few of them won’t work
properly on your computer.
</para>
<para>
If you are familiar with reporting bugs in software,
you can help out by reporting the problem to the developers,
see <ulink url="http://www.debian.org/Bugs/Reporting">
http://www.debian.org/Bugs/Reporting</ulink> for
information on how to report a bug in Debian. If you do not
run Debian, but a distribution based on it, you might need to
report the bug to another address.
</para>
<para>
Otherwise, look through the Center for another program to do what you want.
