Could you add the license to the repository?

[Racheet]

I'm really grateful for this resource, and the permissive terms you've licensed it under, but currently the license terms are only shown on the linked webpage.

If that page were to go down, it wouldn't be clear from the codebase that it was ok to use it. Is there any chance you could put the text from that webpage as a LICENSE file in the repository so everything is all in one place?
