Hi, you only need to put the extracted folder in the "Mods" folder of cyf and then you should be able to see it in the mods selection screen of cyf.
This didnt work for me. IDK why.
If the only problem is that the mod isn't showing up in cyf's selection screen, then you probably put the zipped folder in there. You need to unzip it first to see it in the mods' selection screen.
