# llms.txt guide for AI agents and GEO — ADN — ADN

← Back to Learn llms.txt is a plain-text file at your domain root that tells AI agents and crawlers where to find your most important content. Think of it as a curated reading list for machines.
 Why llms.txt matters for GEO
 Answer engines and IDE agents do not browse like humans. They need:
 • A clear starting point (homepage, docs index, API reference)
 • Short descriptions of what each link contains
 • Hints about which pages are authoritative vs supplementary
 Without llms.txt, agents guess from your sitemap or scrape navigation — often missing the page that answers the user's question.
 Format
 llms.txt uses Markdown-style headings and link lists:
 # Your Company
> One-line description of what you do.
 Docs
 • Getting started : onboarding guide
 • API reference : REST endpoints
 Product
 • Pricing : plans and limits
Keep it concise. Agents read the whole file in one fetch.
 What to include
 1. Site summary — One blockquote describing your product or publication.
 2. Key sections — Docs, product, help, legal — with 3–8 links each.
 3. Descriptions — After each link, a short clause on what the page contains.
 4. Optional: contact — Support email or status page for agents that need escalation.
 Skip marketing fluff. Machines want signal.
