+## Running inside docker
+If you want to generate a graph for a remote system you can also easily

+    
+    docker run -v /var/run/docker.sock:/var/run/docker.sock leoverto/docker-net-graph

+graphviz installed, paste the previous output there, press enter
+and finally CTRL+C to generate the file.
