+                    LNURL is a range of lightning-network standards that allow
+                    us to use lightning-network differently. An LNURL-pay is a
+                    link that wallets use to fetch an invoice from a server
+                    on-demand. The link or QR code is fixed, but each time it is
+                    read by a compatible wallet a new QR code is issued by the
+                    service. It can be used to activate machines without them
+                    having to maintain an electronic screen to generate and show
+                    invoices locally, or to sell any predefined good or service
+                    automatically.

+                    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.
