+    <h1>About</h1>
+    <p>
+      <a href="https://www.bittorrent.org/beps/bep_0005.html">DHT</a> is a
+      powerful technology that enables "trackerless" torrents; however, there
+      are a number of reasons why a client may be unable to join the DHT swarm
+      such as local or ISP blocking. This server acts as a gateway to discover
+      clients that have announced to the DHT network, and provides a
+      tracker-compatible interface for ease of use.
+    </p>
+    <h1>Usage</h1>
+    <p>
+      You will most likely want to add
+      <code>https://dht.terrible.network/fetch</code> to the list of trackers in
+      your torrent client.
+    </p>
+    <p>
+      In addition to supporting "compact" representation
+      (<code>?compact=1</code>) this service also supports "json" representation
+      (<code>?json=1</code>) for ease of use in code.
+    </p>
+    <h1>FAQ</h1>
+    <h2>So is this just a BitTorrent tracker?</h2>
+    <p>
+      No. This server does not collect/store the information necessary to act as
+      a tracker (IP address, "port" parameter), it does not serve anything other
+      than information queried from the DHT.
+    </p>
+    <h2>Will this announce me to the DHT?</h2>
+    <p>
+      No. This server does not collect the information necessary to do so (IP
+      address), and it is technologically impossible to announce an IP other
+      than one owned by the machine speaking to the DHT swarm.
+    </p>
