Character Attribute System

So how do I install this? The “Add to project” doesn’t add to a project and instead wants to create a new project. If I try to add it inside my content folder or project folder it doesn’t work as in i get a bunch of compile errors. Also it’ll show the character system as a project by itself in my library.

*edit i just created a new project and copied over the content folder, it got rid of my errors at least.
