Can you provide more information on how to run the "Bruxelles demo"?

"Change to Host's IP" -> what's "Host" ?
make build-images work ok for me.
make registry-login fails for me.

echo "Logging in to HDAR located at http://10.0.3.53:5000..."
Logging in to HDAR located at http://10.0.3.53:5000...
hdarctl login http://10.0.3.53:5000
make: hdarctl: No such file or directory
make: *** [registry-login] Error 1

I guess hdarctl must be installed before. Could you add indications on how to do that in the README?
