Paper on Multicraft

Hi, I am new to this so bear with me if this sounds like a stupid question. I am running a vm with 2 8 core procs assigned with 40 gigs of memory. On the vm I am running windows 7 and the newest release of multicraft. I started the server using bukkit and found out about paper from the server console. My problem is that I am unsure how to get multicraft to run paper and their custom jar directions are pretty confusing. Is there someone here that knows how to make this run or knows where I can find a step by step video? Thanks in advance for your help.

Don’t you have access to the craftbukkit.jar? Remove it and replace it with paper.jar and rename it to whatever the craftbukkit.jar was named to or change the startup arguments to whatever the paper.jar is named to.
