Hi @yhoebeke! Welcome to netlify community.
You can make yorgo.art your main domain here in the netlify dashboard: https://app.netlify.com/sites/boilerman-phyllis-72260/settings/domain#custom-domains
I’ve added the domain to your dashboard for you, but you’ll need to set it as your primary domain. Then, if you want to continue using Netlify to manage your DNS, you’ll want to make sure you are using the Netlify name servers found here: https://app.netlify.com/teams/rhydderch/dns/yorgo.me#nameservers
Finally, to redirect, those instructions are just below the custom domain instructions in your dashboard (my first link above).
Let us know how it goes!
