ldc2 windows10 64 bit - ldc2/lld what is needed to be installed?

[Carl Sturtivant]

I want to get a student (who is running Windows 10 64-bit on 
their laptop) up and running with ldc2 using lld. And I'd like to 
avoid installing anything not absolutely necessary.

Can you point me to some up-to-date docs for ldc2 that explain 
the current situation on Windows? Or tell me a minimum that needs 
to be installed to support writing command-line programs that are 
not Windows applications as such.
