  <para>
    This wiki's pages are written in
    <ulink url="http://johnmacfarlane.net/pandoc">pandoc</ulink>'s
    extended form of
    <ulink url="http://daringfireball.net/projects/markdown">markdown</ulink>.
    If you're not familiar with markdown, you should start by looking at
    the
    <ulink url="http://daringfireball.net/projects/markdown/basics">markdown
    &quot;basics&quot; page</ulink> and the
    <ulink url="http://daringfireball.net/projects/markdown/syntax">markdown
    syntax description</ulink>. Consult the
    <ulink url="http://johnmacfarlane.net/pandoc/README.html">pandoc
    User's Guide</ulink> for information about pandoc's syntax for
    footnotes, tables, description lists, and other elements not present
    in standard markdown.

  <para>
    Markdown is pretty intuitive, since it is based on email
    conventions. Here are some examples to get you started:

## Some examples...

Text...
</programlisting>
  <sect2 id="wiki-links">
    <title>Wiki links</title>
    <para>
      Links to other wiki pages are formed this way:
      <literal>[Page Name]()</literal>. (Gitit converts markdown links
      with empty targets into wikilinks.)
    </para>
    <para>
      To link to a wiki page using something else as the link text:
      <literal>[something else](Page Name)</literal>.
    </para>
    <para>
      Note that page names may contain spaces and some special
      characters. They need not be CamelCase. CamelCase words are
      <emphasis>not</emphasis> automatically converted to wiki links.
    </para>
    <para>
      Wiki pages may be organized into directories. So, if you have
      several pages on wine, you may wish to organize them like so:
    </para>
    <programlisting>
Wine/Pinot Noir
Wine/Burgundy
Wine/Cabernet Sauvignon
</programlisting>
    <para>
      Note that a wiki link <literal>[Burgundy]()</literal> that occurs
      inside the <literal>Wine</literal> directory will link to
      <literal>Wine/Burgundy</literal>, and not to
      <literal>Burgundy</literal>. To link to a top-level page called
      <literal>Burgundy</literal>, you'd have to use
      <literal>[Burgundy](/Burgundy)</literal>.
    </para>
    <para>
      To link to a directory listing for a subdirectory, use a trailing
      slash: <literal>[Wine/]()</literal> will link to a listing of the
      <literal>Wine</literal> subdirectory.
    </para>
