How would I make a skinned mesh ocean?

I have seen games where they use something called a skinned mesh ocean or something. I'm trying to figure out how to do that, but am not sure. I don't really know anything about scripting (except the basic stuff) and so a lot of definition would be very helpful. I also have like no experience with Blender but can do basic operations. I also have no experience with skinned meshes but kind of understand (just a little). Please help!

here is the forum page I saw where they talked about it a little: https://devforum.roblox.com/t/seamless-endless-and-performant-custom-water-using-skinned-meshes-and-pbr/832505
