+# RoboSats app for soverign nodes.
+
+RoboSats app for soverign nodes ( Umbrel, Citadel, Start9 ...). This app serves the RoboSats frontend app directly from your own node and redirects all API requests to RoboSats P2P market coordinator through your node's TOR proxy.
+
+At the moment it has no special integration with your local lightning wallet (e.g. LND). This can be achieved easily by installing a WebLN compatible extension in your browser (e.g. getAlby).
+
+The container launches two processes: 1) A `socat` that will expose RoboSats coordinator API over HTTP using the docker orchestration Tor socks proxy and 2) a `http-server` that will serve all static files (including the Javascript client app) directly from your own node (should reduce loading times by a lot). Every request that cannot be served by your node http-server will be forwarded to the RoboSats coordinator (that is: API calls and Robot avatar images).
