+### Public tracker + WSS relay
+
+For internet nodes, expose one public HTTPS host and proxy these paths:
+
+```text
+/v1/*   -> meshnet-tracker, for registration, heartbeats, routing, and OpenAI requests
+/ws     -> meshnet-relay, for outbound node gossip/bridge connections
+/rpc/*  -> meshnet-relay, for tracker-to-node relay requests
+```
+
+Start the tracker with the public relay URL it should advertise:
+
+```bash
+.venv/bin/meshnet-relay --host 0.0.0.0 --port 8765
+.venv/bin/meshnet-tracker start \
+  --host 0.0.0.0 \
+  --port 8081 \
+  --relay-url wss://ai.neuron.d-popov.com/ws
+```
+
+Then a node only needs the public tracker address:
+
+```bash
+.venv/bin/meshnet-node start \
+  --tracker https://ai.neuron.d-popov.com \
+  --model-id Qwen/Qwen2.5-0.5B-Instruct
+```
+
