How to install a leaked UE4 asset?

I downloaded the medieval village asset, and it comes with all the content files...
but there is no manifest so i can't add it to my vaultcache...

and if i try to add a .uproject file from another folder to its folder, it loads up but all the meshs have no materials...

I have no idea how im suppose to utilize this, or any other leaked asset assuming they are all the same?

a bit of a newb, any help is appreciated guys, idk where else to ask.
