After signing up for an account with us, you will simply need to update your domain name servers (DNS) at the company with which your domain is held (unless the domain itself has been transferred to us as well) with the information that you would have received with your account information email (ns1.sinohosting.net/ns2.sinohosting.net, ns3.sinohosting.net/ns4.sinohosting.net etc.). Usually it takes less than 24h for the DNS to update over the Internet for the site to be live on our servers.
For the practical steps on moving a site contents to our servers, please read the following article on our blog.
