+This example shows how to use the network_mode option to use the network defined
+by other container. This is useful for example to allow the CI to connect with servers
+behind a VPN.
+
+Before to start you need to create a container that connects to the VPN (using one of
+the openvpn client images like https://github.com/ekristen/docker-openvpn-client).
