For us to begin hosting your website, you will need to login with your current domain registrar and change your Name Servers (basically a pointer to our server). This is not changing who owns the domain, or where it is registered.
Be sure to always pay your domain registrar and while you are logged in, double check it is on Auto-Renew.
Find your domain, then locate a setting called DNS (or Name Servers). These pictures are from a GoDaddy account but every registrar has this setting somewhere.
Here you will see your current Name Servers. Hit the Change button.
