We'll handle your domain configuration for you. When you're ready to do so, contact SoloFolio support via the Account page and we'll take care of the process.
We highly recommend that you attach a custom domain name to your SoloFolio site. SoloFolio does not provide domain registration services, as it is in your best interest to own and manage your domain name directly. We recommend buying a domain with Google Domains. However, any registrar that allows full DNS management will work.
