# Lumen Night Reader > Notes on systems, tooling, and the quiet art of keeping software honest. ## Content format Every post is available as plain Markdown at a mirrored path: - HTML: `/posts//` - Markdown: `/api/md/posts//index.md` Pattern: prepend `/api/md` to any post URL and append `index.md` to receive `text/markdown`. Front matter is stripped. Content is the raw Markdown source. HTML pages declare the alternate in ``: ``. ## Indexes - Home, section, taxonomy, term pages — HTML only (no Markdown output) - Full list of Markdown endpoints: [`/sitemap-markdown.xml`](/sitemap-markdown.xml) - [Sitemap (HTML)](/sitemap.xml) - [Sitemap (Markdown endpoints)](/sitemap-markdown.xml) - [RSS](/index.xml) ## Notes - Only `page` kinds emit Markdown output. Section, taxonomy, and term pages are HTML-only. - URLs are deterministic — no need to scrape `` if you already know a post path.
