Step By Step for Impact Arena?

[CuddlyCorey]

Okay, so on 2KM there is a great Impact arena mod by "Blxckheart" here: Impact Arena by Blxckheart on 2KM

But, omgawd...It's really confusing. Like, almost mindblowing. 

Can someone do a step-by-step on how to actually get this mod to work? 

I noticed they refer to "Abhilash's Ported Arena Mod" that this arena overwrites, but I never installed that mod, and I don't want too, because I already have other arena's installed. 

Also, for the matchcard thing, I have that mod, and the tutorial seems straighforward enough, but still gets lost in translation. 

HELP! LOL
