How can I get the Greenfeldt PowerShell MA to install?

Hi,

Can someone advise me how I can get the Greenfeldt PowerShell Management agent to install?

I've followed the brief instructions from http://blog.goverco.com/p/powershell-management-agent.html

I have the DLL, put it in my extensions folder and created a new extensible MA, however the bit I'm struggling with is "Make sure to modify the schema discovery file before configuring the MA "

Please can someone tell me how to do modify the schema to get this to work?

Thanks
