Ask HN: Any good plug'n'play static site generators for docs?

I have been searching for a good and simple to use static site generator to generate documentation for one of my projects. The problem is all the good ones (docsaurus, nextra etc.) require complex setups. I know it's simple for a developer but I want it to be easy for contributors to preview their changes. Not everyone has a NodeJS setup.

I know GitBook exists but it's not OSS and is fairly complex on its own: a whole platform with its own learning curve.

I am looking for something that can:

- generate documentation from markdown - minimal but modern design (doesn't have to be configurable) - zero setup/dependencies i.e. plug'n'play

Here's the workflow I am looking for:

- clone

- install xyz for platform

- make edits

- xyz dev/start

I have explored Hugo and Zola but I don't like the multiple directories they create for themes, CSS, js etc. I want the generator to be self-contained.

The reason I am here asking is if someone has a personal project that does something like this that they'd like to share. Or if someone is working on something similar and would like users.
