# Legacy Material The original symusic documentation lives in an mdBook under `docs/src`. It still covers important concepts, but several APIs mentioned there have been renamed or removed. - Live site: - Sources: `docs/src/*.md` We will progressively port the useful parts into this Sphinx site. In the meantime: - Treat mdBook snippets as historical context rather than the source of truth. - Prefer the tutorial pages here once they appear—they will be tested against CI. - If you discover inaccuracies in mdBook pages, open an issue referencing the page so we can fold the fix directly into the MyST version instead of patching the legacy copy.
