Short tutorial about revolution case update?

[larinhagoddess]

Hello! I use the knife and weapons plugins for a while on my server (dathost). But I am not able to install the new skins plugin. Can anyone help me, maybe with a short tutorial? I currently have gloves v-1.0.5 and weapons v-1.7.7 (recoil case update) installed. I want to use the revolution case update, but when I download the .zip, it's named "weapons-master.zip" and I don't know what to do next. The other times I downloaded the .zip of the version directly and put it on the server. This time I don't know what to do =)
