+  <description>
+    <p>Haveno (pronounced ha‧ve‧no) is a platform for people who want to exchange Monero for fiat currencies like EUR, GBP, and USD or other cryptocurrencies like BTC, ETH, and BCH.</p>
+    <ul>
+      <li>All communications are routed through  Tor, to preserve your privacy
+      </li>
+      <li>Trades are peer-to-peer: trades on Haveno will happen between people only, there is no central authority.
+      </li>
+      <li>Trades are non-custodial: Haveno provides arbitration in case something goes wrong during the trade, but we will never have access to your funds.
+      </li>
+      <li>There is No token, because we don&#39;t need it. Transactions between traders are secured by non-custodial multisignature transactions on the Monero network.
+      </li>
+    </ul>
