 # Nostr Wallet Connect (Next)

 This application allows you to control your Lightning node or wallet over Nostr.
 Connect applications like [Damus](https://damus.io/) or [Amethyst](https://linktr.ee/amethyst.social) to your node.
 
 **Specification**: [NIP-47](https://github.com/nostr-protocol/nips/blob/master/47.md)
 
+The application can run in two modes:
+
+- Wails (Desktop app): Mac (arm64), Windows (amd64), Linux (amd64)
+- HTTP (Web app): Docker, Linux (amd64)
+
+Ideally the app runs 24/7 (on a node, VPS or always-online desktop/laptop machine) so it can be connected to a lightning address and receive online payments.
