Select the "inet" value from the output

go to https://cloud.digitalocean.com/networking/domains and select "rhobot.net" Add a DNS entry for demoapi to the "inet" address from above Add a DNS entry for demoadmin to the "inet" address from above Add a DNS entry for demo to the "inet" address from above

su - rchain -c "git clone http://github.com/rchain-community/liquid-democracy"
su - rchain -c "mkdir ~/liquid-democracy/dist"
certbot certonly -d demoapi.rhobot.net
   Select (1)
certbot certonly -d demoadmin.rhobot.net
   Select (1)

wait until DNS updates (use dig to verify)
