Can't Add a c# script, it says is abstract!

Hi guys! i’m trying to implement a script inside my project but when i try to attach it to an empty gameObject it show up this message.

this is he CS script:

The problem is that this script is a static class that does not inherit from MonoBehaviour and thus cannot act as a component on an object.
You can still use it from code (since it’s static) but you cannot attach it to an object.

Judging from the content, you don’t want to do that anyway.
