Getting MDF/MDS to Work in ePSXe

I have a MDF and a MDS file for a game but I'm unsure as to how I'm suppose to get it to work in ePSXe. Can someone help?

Version 1.7.0 of ePSXe supports MDF/MDS files.Otherwise you can use a program like Daemon Tools to mount the image to a virtual drive and have ePSXe treat it like a real CD.
