 After meshcore_multitcp is running you can connect your clients to IP/port set with -s
 
+## docker
+
+```bash
+# build
+docker build -t meshcore-multitcp .
+
+# run
+docker run -p 5000:5000 meshcore-multitcp -d Device-IP:PORT -s 0.0.0.0:5000 [-q|-v]
+```
+
+### docker compose
+
+Copy and edit `docker-compose.yml` to match your setup:
+
+- `-d` - IP and port of your companion radio
+- `-s 0.0.0.0:PORT` - port the proxy listens on for clients (always use `0.0.0.0` inside the container)
+- `-f 0.0.0.0:PORT` - port for store & forward clients (requires `-sql`)
+- `ports` - use `host-ip:port:port` to bind to a specific host interface, or `port:port` for all interfaces
+- `volumes` - mount a host path to `/data` to persist the SQLite database across restarts
+
+```bash
+docker compose up -d
+```
+
 ## S&F - store & forward messages
 
 Using option -sql meshcore-multitcp will store all incomming private & channel messages in local sqlite3-database.
