Projects with Great Documentation

I'm looking to compile a list of projects with great documentation so as to provide examples to contributors and maintainers for Hacktoberfest.

Some projects with great documentation that come to mind are React and Vue.

What's a project that you know of that has great documentation?

tsParticles uses typedoc to create basic documentation, I created also a customized theme with markdown support to add custom pages with more details, readme are also a good point to start.

github.com/matteobruni/tsparticles

I’m updating that right now and if someone has some good ideas is welcome to contribute

Rust has one of the best language documentation I have come across :
doc.rust-lang.org/std/index.html
doc.rust-lang.org/book/
Rust-wasm has really great 'getting started' docs : rustwasm.github.io/docs/book/intro...
Rustling course has a nice readme : github.com/rust-lang/rustlings
