VERDICT

Should I use Just the Docs?

Just the Docs is a responsive Jekyll theme with built-in search that is easily customizable and hosted on GitHub Pages. - just-the-docs.com

Worth it. Buy it if your team writes Markdown and is comfortable running Jekyll on GitHub Pages — it's free, flexible, and proven at major-company scale. Skip it if you want hosted, WYSIWYG documentation or have nobody who can debug a Ruby build.

Confidence

High. Based on 20+ public sources: official docs, GitHub, Reddit/Stack Overflow threads, and security pages.
