If you want to add a domain to your site you can buy one directly from Cargo: Publish Settings → Add a Domain → Buy a new Domain
Once you’ve purchased a domain, it will take a little bit of time for the domain to propagate, after which it will be connected to your site automatically. You’ll receive an email when this is completed.
NB: domain name purchases are non-refundable, and are not included in a Cargo Subscription.
DNS editing
Cargo offers basic DNS editing capability; this allows you to link third-party services (such as filehosting or email) to your domain. Learn more here.
