Dorktoid

I’m fascinated by this mod and would love to give it a try. I’m new to modding Reborn in general. I see this is an .rb file which makes it look like a script, so I stuck it in the Scripts folder and it didn’t seem to work. Which leads me to feel like I missed something, but I can’t find instructions in the OP. I’m sorry if this was assumed or if it’s described elsewhere - or if it’s right here and I selectively forgot how to read - how do I install this mod?
