llms.txt

What is llms.txt?

llms.txt is a plain-text file at a site's root that summarises the site and lists its most important pages for large language models to ingest.

Why it matters

It is a community convention rather than an official standard, but it costs almost nothing and gives AI crawlers a clean map of your best content.

Pair it with an llms-full.txt containing the full text of your key pages.
