  <title>Add a Personal Package Archive (PPA)</title>
  <p><em>Personal Package Archives (PPAs)</em> are software repositories designed
  for Ubuntu users and are easier to install than other third-party repositories.</p>

  <note style="warning"><p>Only add software repositories from sources that you trust!</p>
  <p>Third-party software repositories are not checked for security or reliability by Ubuntu
  members, and may contain software which is harmful to your computer.</p></note>

  <steps>
    <title>Install a PPA</title>
      <item><p>On the PPA's overview page, look for the heading <gui>Adding this PPA to your system</gui>.
        Make a note of the PPA's location, which should look similar to: <code>ppa:mozillateam/firefox-next</code>.</p></item>
      <item><p>Click the <app>Ubuntu Software Center</app> icon in the <gui>launcher</gui>,
        or search for <input>Software Center</input> in the <gui>dash</gui>.</p></item>
      <item><p>When the Software Center launches, click <guiseq><gui>Edit&gt;</gui><gui>Software Sources</gui></guiseq></p></item>
      <item><p>Switch to the <gui>Other Software</gui> tab.</p></item>
      <item><p>Click <gui>Add</gui> and enter the <code>ppa:</code> location.</p></item>
      <item><p>Click <gui>Add Source</gui>. Enter your password in the Authenticate window.</p></item>
      <item><p>Close the Software Sources window. Ubuntu Software Center will then check
        your software sources for new software.</p></item>
  </steps>
