+
+  The module can listen direclty to dhcp broadcast messages or listen to redirected openwrt dhcp log messages.
+
+  Notes:
+  <ul>
+    <li>if listening for dhcp messages the module has to run as root or you have to redirect port 67 with
+<ul><code>iptables -A PREROUTING -t nat -i eth0 -p udp --dport 67 -j REDIRECT --to-port 6767</code></ul>
+or
+<ul><code>iptables -I PREROUTING -t nat -i eth0 -p udp --src 0.0.0.0 --dport 67 -j DNAT --to 0.0.0.0:6767</code></ul>
+and use the port attribute to configure the redirected port.</li>
