There are two ways to make your existing domain name work with our hosting service.
The first one is just to change the DNS servers for your domain to the ones mentioned in our welcome email. You can do that at the place where you have registered your domain name, and it's free.
The other possibility is to transfer your domain name to us.
The transfer usually takes about 5 working days (there is no downtime), and your domain name registration is prolonged for one more year. For example, if you transfer yourdomain to our service, we will charge you for 1 years renewal (as per ICAAN rules) and will transfer and also renew your domain name for one more year.
