	<h2>
		Quick guide
	</h2>
		<p>
			Set up two virtual computers - SimpleArbiterDhcp and FileServer.
		</p>
		<p>
			Make sure that the directory /srv/nfs/ERLbbBrT on FileServer is accessible
			over NFS and over SMB under the sharename urania-03.
			Set the SMB server name to zarptica-32.
		</p>
		<p>
			SimpleArbiterDhcp should have write access to /srv/nfs/ERLbbBrT over NFS.
		</p>
