 **Configuration:**
 
-You can specify the Docker socket path using the `--docker-socket` CLI argument or by setting the `DOCKER_SOCKET` environment variable. On most linux systems the socket is `/var/run/docker.sock`. When deploying newt as a container, you need to mount the host socket as a volume for the newt container to access it. If the Docker socket is not available or accessible, Newt will gracefully disable Docker integration and continue normal operation.
+You can specify the Docker socket path using the `--docker-socket` CLI argument or by setting the `DOCKER_SOCKET` environment variable. If the Docker socket is not available or accessible, Newt will gracefully disable Docker integration and continue normal operation.

+Supported values include:

+-   Local UNIX socket (default):

+    `unix:///var/run/docker.sock`
+
+-   TCP socket (e.g., via Docker Socket Proxy):
+    `tcp://localhost:2375`
+
+-   HTTP/HTTPS endpoints (e.g., remote Docker APIs):
+    `http://your-host:2375`
+
+-   SSH connections (experimental, requires SSH setup):
+    `ssh://user@host`
