如何设置报表服务器实例？

I'm trying to set up Microsoft SQL Server Reporting Services. I open the Reporting Services Configuration Manager, and it asks for a Server name. Thing is, I don't know the server name, because as far as I know haven't set a report server up yet. So, how do you set one up for Microsoft SQL Server 2008 R2? There seems to be plenty of documentation out there how to configure one, but not how to install a new instance.I'm trying to set up Microsoft SQL Server Repor
