Adding a custom domain
Type it into Settings - then complete DNS setup and verification.
From Settings → Domains, enter the domain you own and add it. This alone doesn't make it usable - you still need to complete DNS setup and verification before it's ready to use on links.
A hostname can only be claimed by one GoloLink account at a time - if it's already in use elsewhere, adding it will fail.
