For PGXN, I have used a README.md for a readme (briefly about the extension, 
how to build and install it), and a doc/$extension.md file for documentation on 
the usage of the extension. Quite a few people put all of that into the README, 
though.

I think COMMENT is a bit lightweight for detailed documentation. I often write 
a lot of detail, including examples, summarizations, tutorials, etc., not just 
brief explanations of what each object is.
