+      <p>
+        <b>WARNING: LNURL must be used over https or TOR</b><br />
+        LNURL is a range of lightning-network standards that allow us to use
+        lightning-network differently. An LNURL withdraw is the permission for
+        someone to pull a certain amount of funds from a lightning wallet. In
+        this extension time is also added - an amount can be withdraw over a
+        period of time. A typical use case for an LNURL withdraw is a faucet,
+        although it is a very powerful technology, with much further reaching
+        implications. For example, an LNURL withdraw could be minted to pay for
+        a subscription service.
+      </p>
+      <p>
+        Exploring LNURL and finding use cases, is really helping inform
+        lightning protocol development, rather than the protocol dictating how
+        lightning-network should be engaged with.
+      </p>
