Docs and README tools

I want to pick an open-source replacement for GitBook, ReadMe, Mintlify (writing project documentation sites, badges and readmes). Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - MkDocs: MkDocs turns plain text files written in Markdown into a website for project documentation. It is for programmers and project teams who want to publish guides and manuals. [Advanced setup; devices not listed; replaces fully; BSD-2-Clause; no changes in over a year; https://github.com/mkdocs/mkdocs] - Docusaurus: Docusaurus is a free tool that builds websites for open source projects, such as documentation sites, from simple text files. It is made for programmers and project teams who want to publish project documentation and guides. [Advanced setup; devices not listed; replaces partly; MIT; https://github.com/facebook/docusaurus] - Starlight: Starlight is a tool for building documentation websites, the kind of help pages and guides that explain how a product or project works. It is made for developers and teams who want to publish clear documentation sites. [Advanced setup; devices not listed; replaces partly; MIT; https://github.com/withastro/starlight] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/dev-docs.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/dev-docs.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
