What makes an llms.txt valid?

• Starts with a single # Title (H1) naming the site or project.
• An optional > blockquote summary right under it — the line AI engines quote first.
• ## Sections (level-2) grouping your key pages, e.g. ## Docs, ## API, ## Optional.
• Link lists as clean markdown: - [name](https://full-url): optional notes.
• Plain Markdown — no raw HTML — and concise (put the full dump in llms-full.txt).
