The two most popular options are Docusaurus and Material MkDocs:

- https://docusaurus.io

- https://squidfunk.github.io/mkdocs-material/

They're both used by hundreds of open source projects, are pretty easy to set up, and use markdown for content so you shouldn't have any trouble.

A lot of static site generators support rendering markdown to HTML, can't give any specifics since you probably have your own preferred stack/language to use.

imo gitbook.com seems to be the easiest for nondevs

What’s the complexity of your project? If you’re not a developer and it’s a simple project, I’d say do notion pages.

If devs like it I’m sure they will contribute to make a legit docs site for it.

Good way to start imo that has zero friction (for you) and I wouldn’t personally mind it since you get public URL’s.

Or use Codex or CC to make a markdown site hosted on GitHub io
