+## Running inside docker
+If you want to generate a graph for a remote system you can also easily
+run this script inside a pre-built docker container:
+    
+    docker run -v /var/run/docker.sock:/var/run/docker.sock leoverto/docker-net-graph

+This will just generate and output the graph. You can then run
+`dot -Tpdf -o out.pdf`or `dot -Tpng -o out.png` on a system with
+graphviz installed, paste the previous output there, press enter
+and finally CTRL+C to generate the file.
