By adjusting the query string parameter in the URL, partners can remove branding from the OEM Installer page, 

Standard URL - oemserver.com/installer

Example - https://www.oemserver.com/installer?Name=WhiteLabel

By adding ?Name=<partnername> the page name will be changed and all branding is removed.

This can be used to allow end users to conduct their own testing at a page without Digital Matter branding.
