    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</code> gets you

    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>

<li>If you have made any changes to your <code>wrapper.config</code>, please back

    to your JVM, do so now)</li>
