Replaces these SaaS

GitBook · Documentation hosting / knowledge base
Run `npx create-docusaurus@latest my-docs classic`. GitBook export → git → drop the .md files into `docs/` — Docusaurus picks them up. Images live alongside; rewrite GitBook-specific block syntax (hints, tabs) to Docusaurus's MDX equivalents. Docs are git-versioned; every change is a PR.
