If you already own a domain name at another registrar and you do not wish to transfer, then you can set the DNS records to point to the IP address of your webshop.
Setting DNS records is quite technical. If you have any questions about this topic, it's best to contact your current domain name registrar: we cannot provide support for settings at external parties.
If you simply want to connect your domain name without technical procedures, we recommend transferring the domain name.
You will now see the instructions for connecting your domain name.
