How do I create a Catalina fresh installer

Trying to create a Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina fresh installer using OpenCore. Any ideas on how to do this. Tried using clover and created a usb installer, it reports that it will not install.

I have read the OpenCore documents and can not figure out how to create the configuration file without having the machine I want to Hackintosh booted in to a OS.

Please help.
