If you will be using your own domain, you will need to update your nameservers from your provider to the following ISODME nameservers:
jackson.ns.isodme.com
jack.ns.isodme.com
justin.ns.isodme.com
jacob.ns.isodme.com
jonathan.ns.isodme.com
Nameservers are servers that relay information about the location of the server to handle requests, so without switching your nameservers, your visitors will not be able to access the ISODME server that serves the website files.
