What is the benefit of GitHub Sponsor?

I remember reading the article? or something about GitHub Sponsor, and it says that sponsors get benefit according to its amount, such as getting sponsor badge? or being listed on the users’ sponsors.

If there is the document about it, I want to read it.

Thanks.

Sorry for my forgetting.
This may be the answer:

For each tier you’ll receive a badge that shows @resotto you’re a sponsor. Hover over your avatar to see.
