SoundFont instillation

So I use musescore for recreational purposes but I downloaded the 2.0 beta cuz why not. I was very unhappy with the drum set sounds so I looked online for instruction as to how to put a soundfont onto my score. I have absolutely no computer skills except that I can, you know, move around file and stuff. Can someone please give me a blow-by-blow to getting a soundfont on my score with the starting point being this: I downloaded the hard rockers drumkit soundfont from sf2midi.com. It is on my computer under downloads now how do I put it in the synthesizer and onto my computer in musescore 2.0 beta? Help is much appreciated, thanks!
