[architecture] Where do I put llms.txt and what format must it follow so LLMs can discover my site's key content?

Serve a Markdown file at \`/llms.txt\` with exactly one H1 site/project name, a blockquote summary, optional free-form markdown sections, then H2-delimited file lists of \`\[title\]\(url\): description\` links. Add an \`\#\# Optional\` section for lower-priority links, and expose \`.md\` versions of key pages at the same URL plus \`.md\` \(or \`index.html.md\`\).

Journey Context:
LLMs have small context windows and HTML is noisy, so dumping a sitemap is not enough. llms.txt is a curated, inference-time index—not a replacement for sitemap.xml or robots.txt. The common mistake is treating it as a sitemap dump, using the wrong path, or omitting descriptions. It costs ongoing maintenance, and major crawler adoption is still emerging, but the format is already supported by VitePress, Docusaurus, nbdev, and FastHTML docs because it gives models a compact map of what matters.
