    <para><application>Git</application> is a free and open source, distributed
    version control system designed to handle everything from small to very
    large projects with speed and efficiency. Every
    <application>Git</application> clone is a full-fledged repository with
    complete history and full revision tracking capabilities, not dependent on
    network access or a central server. Branching and merging are fast and easy
    to do. <application>Git</application> is used for version control of files,
    much like tools such as <application>Mercurial</application>,
    <application>Bazaar</application>, <xref linkend="subversion"/>,
    <xref linkend="cvs"/>, <application>Perforce</application>, and
    <application>Team Foundation Server</application>.</para>

    <para>If you have installed <ulink

    pages and other docs:</para>

<screen><userinput>make html</userinput></screen>

    <para>To check the results, issue: <command>make test</command>.</para>

    <para>Now, as the <systemitem class="username">root</systemitem>
    user:</para>

    <para>If you created the man pages, install them as the

    <para><option>-&#45;with-gitconfig=/etc/gitconfig</option>: This sets
    <filename>/etc/gitconfig</filename> as the file that stores the default,
    system wide, <application>Git</application> settings.</para>

    <para><command>tar xf ../git-manpages-&git-version;.2.tar.gz -C
    /usr/share/man --no-same-owner</command>: This untars
    <filename>git-manpages-&git-version;.2.tar.gz</filename>. The
    <option>-C</option> option makes tar change directory to
    <filename class="directory">/usr/share/man</filename> before it starts to
    decompress the docs. The <option>--no-same-owner</option> option stops tar
    from preserving the user and group details of the files. This is useful as
    that user or group may not exist on your system; this could
    (potentially) be a security risk.</para>

    <para><command>mv /usr/share/doc/git-&git-version; ...</command>: These
    commands move some of the files into subfolders to make it easier to sort
    through the docs and find what you're looking for.</para>
