+### Docker
+To run pyja3mas as a Docker container, first build the Docker image with:
+`docker build -t pyja3mas .`
+
+Then run the container with:
+`docker run -p 127.0.0.1:443:4443 pyja3mas`
+
+This will listen on port 443 of your loopback adapter for connections and
+forward them to the running pyja3mas script inside the container.
