What are the best GitHub READMEs you've seen?

The table layout and example formatting of "The Universal Route Module API Specification" is quite good: https://github.com/fastify/fastify-dx/blob/main/URMA.md

This one is pretty neat:

It's not an app README, but a profile one. A lot of it is done with images.
