"ProjectDir\(Difficulty)_Scripts" doesn't exist, so where do i install scripts?

the website says "Download scripts and extract them, then copy them to ProjectDir\(Difficulty)_Scripts" but ProjectDir\(Difficulty)_Scripts doesn't exist anywhere on my pc. how do i install scripts?

When you start a new project it's respective folder will be created, inside it you'll find it's respective difficulty folders.
P.S. scripts are for score creators
