Can someone give me simple instructions on how to build 64-bit DMD using Visual Studio?

I've read through the available documentation, but it's all 
incredibly brief and vague. What file specifically do I need to 
edit to point to my Visual Studio instance? Should I use 
Win32.mak, or the "VCBUILD" solution? E.t.c.....
