+Newt can integrate with the Docker socket to provide remote inspection of Docker containers. This allows Pangolin to query and retrieve detailed information about containers running on the Newt client, including metadata, network configuration, port mappings, and more.

+- By default, Newt will look for the Docker socket at `/var/run/docker.sock`.
+- You can specify a custom socket path using the `--docker-socket` CLI argument or by setting the `DOCKER_SOCKET` environment variable.
 
-Make sure to `mv ./newt /usr/local/bin/newt`!
+If the Docker socket is not available or accessible, Newt will gracefully disable Docker integration and continue normal operation.
