Hey!
TLDR
You guys are doing a good job so I wanted your advice :)

As part of my job I write programming language (something small for inner use), and I wanted to ask what tool you guys use to document your api, for example:
https://docs.python.org/3/library/argparse.html

I really like that it is version based, there is a search engine, and the general format.

Thanks!,
Elad
