How can I start CentraSite Control?

Hello all,
I try to study and use CentraSite these days. After installed CentraSite , I can see the start page of CentraSite Control and the start page of System Management Hub successfully.
But both pages needs to log on. I don’t know how can I get the account, either from the document. Where can I do the configuration, or what is the initial user account?
Hope for your help.Thank you.

Initial user account is the user account that installed CentraSite - logon userid and password are the logon used to logon to the machine - domain or local admininstrator account.
