    Alternately, you can fetch the source from <a href="cvs">cvs</a> (CVS HEAD
    gets you the most recent updates, while the tag <code>i2p_0_5_0_5</code> gets you
    the release)<br/>
    Run <code>(tar xjvf i2p-0.5.0.5.tar.bz2 ; cd i2p-0.5.0.5 ; ant dist)</code> then either
    run the GUI installer or headless install as above</li>
 <li>After running the GUI install on windows, simply click on the "Run I2P" button
     which will bring up the router console, which has further instructions.  When
     first installing, please remember to <b>adjust your NAT/firewall</b> and
     <b>reseed</b>.</li>
</ul>

<h3>Updates from 0.5.0.4:</h3>
<ol>
<li>With the new announcement system, you should see a link on your 
    <a href="http://localhost:7657/index.jsp">router console</a> allowing
    you to download and install the new release by just clicking on that
    link.  There is a bug in the 0.5.0.4 code though, so you may need to
    delete the file <code>docs/news.xml</code> from your I2P installation
    directory and wait a few minutes for a new news.xml to be retrieved.</li>
<li>Alternately, you can use the instructions specified below.</li>

     <a href="http://dev.i2p.net/i2p/i2pupdate.zip.sig">sig</a>) to your I2P 
    installation directory.
    (alternately, you can get the source as above and run "ant updater", then copy the
    resulting i2pupdate.zip to your I2P installation directory)</li>
