+	      <h4>Setting up the webdav directory</h4>
+	      <p>Add the following lines to the default vhost (in /etc/apache2/sites-available/default):</p>

+
+&lt;/Directory&gt;</pre>
+	      <p>Make sure the group www-data has required rights to modify files in the webdav directory.</p>
+		
+	      <h4>Restarting Apache</h4>
+
+	      <p>To restart Apache, evaluate the following: <pre>~# /etc/init.d/apache2 restart</pre> and go to <code>http://localhost/jtalk/</code>.</p>
+	      <p>The class browser should now be able to commit changes to disk.</p>
