What the best llms.txt files have in common

1. A one-paragraph summary up top (the > blockquote): what the product is, who it is for, in plain words.
2. Grouped links with one-line descriptions: docs, pricing, API reference, integrations, comparisons.
3. Only pages worth reading. It is a curated map, not a sitemap dump.
4. Markdown links an agent can follow, often to .md versions of docs pages, plus an optional llms-full.txt with full text.

What a good llms.txt looks like (annotated)

A complete file for a made-up product, part by part. The structure follows the llms.txt proposal (v2): an H1, a blockquote summary, optional detail, then H2 sections of links.

# Acme Analytics

> Privacy-friendly product analytics for SaaS teams.
> Free up to 10k events a month; paid plans from $20/month.

Acme is hosted in the EU and does not use cookies.
The API is REST with token auth.

## Docs
- [Quickstart](https://acme.com/docs/quickstart.md): install in 5 minutes
- [API reference](https://acme.com/docs/api.md): endpoints and auth

## Product
- [Pricing](https://acme.com/pricing): plans and limits
- [Acme vs Mixpanel](https://acme.com/compare/mixpanel)

## Optional
- [Changelog](https://acme.com/changelog)
- [Blog](https://acme.com/blog)

Per the proposal, the file can also live at a subpath (for example /docs/llms.txt) and then covers the URLs under that path; agents should use the most specific one. Pages can point to their llms.txt with rel="describedby" and to a Markdown version with rel="alternate" type="text/markdown".
