Quick user Tutorial

[CSTufts]

I checked out the Readme, but it doesn't really have a "User Guide". I am getting an Error that

"
Error: 'Xactly.XactlySMBImportScheduler1' is not a valid Apex Class. "

and I don't know how to make this scheduled Apex class into a valid Apex class for your app...

any help would be greatly appreciated!

thanks
