+    <h2>Standards used?</h2>
+    <p>
+        We use:
+        <ul>
+            <li>Frontend Update-API: dyndns2 protocol
+                <ul>
+                    <li><a href="http://dyn.com/support/developers/api/">dyndns2 api description on dyn.com</a></li>
+                    <li><a href="http://www.noip.com/integrate/">dyndns2 api description on noip.com</a></li>
+                </ul>
+            </li>
+            <li>Backend: dynamic DNS update (see <a href="http://www.ietf.org/rfc/rfc2136.txt">RFC2136</a>)</li>
+        </ul>
+    </p>
+    <h2>Easy update URLs</h2>
+    <p>
+        Explanation of parameters:
+        <ul>
+            <li>hostname: your fully qualified hostname, something like example.nsupdate.info</li>
+            <li>yoursecret: the secret you have configured for this hostname</li>
+            <li>IP addresses: we use the v4 and v6 localhost addresses in the examples, but
+                of course you need to use your real public IP instead of that.
+            </li>
+        </ul>
+        For browser / interactive use (will ask for username (give your hostname) and password (give yoursecret)):
+        <ul>
+            <li>http://nsupdate.info/nic/update   (updates hostname to point to remote ipv4 or ipv6 address)</li>
+            <li>http://ipv4.nsupdate.info/nic/update   (updates hostname to point to remote ipv4 address)</li>
+            <li>http://ipv6.nsupdate.info/nic/update   (updates hostname to point to remote ipv6 address)</li>
+        </ul>
+        For browser / interactive use (give http basic auth username and password in URL):
+        <ul>
+            <li>http://hostname:yoursecret@nsupdate.info/nic/update   (updates hostname to point to remote ipv4 or ipv6 address)</li>
+            <li>http://hostname:yoursecret@ipv4.nsupdate.info/nic/update   (updates hostname to point to remote ipv4 address)</li>
+            <li>http://hostname:yoursecret@ipv6.nsupdate.info/nic/update   (updates hostname to point to remote ipv6 address)</li>
+        </ul>
+        For browser / interactive use as above, but manually specifying the IP address:
+        <ul>
+            <li>http://hostname:yoursecret@nsupdate.info/nic/update?myip=127.0.0.1   (updates hostname to point to ipv4 127.0.0.1)</li>
+            <li>http://hostname:yoursecret@nsupdate.info/nic/update?myip=::1   (updates hostname to point to ipv6 ::1)</li>
+        </ul>
+        For routers or other dyndns2 compatible clients:
+        <ul>
+            <li>They must send a http basic auth header with hostname / yoursecret.</li>
+            <li>They must send a GET request to our server: nsupdate.info, path: /nic/update</li>
+            <li>We support http on port 80 (and soon also https on port 443).</li>
+            <li>URL args (all are optional):
+                <ul>
+                    <li>myip=127.0.0.1 or myip=::1  (if not given: autodetect from remote_addr)</li>
+                    <li>hostname=hostname (if not given: autodetect from http basic auth)</li>
+                </ul>
+            </li>
+        </ul>
+    </p>
