+# strfry {#module-services-strfry}
+
+strfry is a relay for the [nostr protocol](https://github.com/nostr-protocol/nostr).
+
+## Basic usage {#module-services-strfry-basic-usage}
+
+By default, the module will execute strfry:
+
+```nix
+{ ... }:
+
+{
+  services.strfry.enable = true;
+}
+```
+It runs in the systemd service named `strfry`.
+
+## Reverse Proxy {#module-services-strfry-reverse-proxy}
+
+You can configure nginx as a reverse proxy with:
+
+```nix
+{ ... }:
+
+{
+  security.acme = {
+    acceptTerms = true;
+    defaults.email = "foo@bar.com";
+  };
+
+  services.nginx.enable = true;
+  services.nginx.virtualHosts."strfry.example.com" = {
+    addSSL = true;
+    enableACME = true;
+    locations."/" = {
+      proxyPass = "http://127.0.0.1:${toString config.services.strfry.settings.relay.port}";
+      proxyWebsockets = true; # nostr uses websockets
+    };
+  };
+
+  services.strfry.enable = true;
+}
+```
