# Guides

In short

Eleven guides cover what decides whether an agent can read a page: seeing the page as a plain-fetch client, checking the initial HTML the way an agent does, returning real status codes, writing llms.txt, serving markdown, JSON-LD, OpenAPI, sitemaps, getting docs cited and testing in CI. Each has sourced facts, steps and a check.
