What is the best way to support Lemmy specifically and the Fediverse in general financially?

I love the Fediverse and Lemmy. But technically, it still lags behind the big platforms in some areas. And there are many things where I believe the Fediverse will eventually be significantly better than centralized platforms, but which are still underdeveloped. Unfortunately, I can't program myself, or at least not very well. So I'm wondering how I can best support development financially.
