The llms.txt file is an industry standard that helps LLMs index content more efficiently, similar to how a sitemap helps search engines. AI tools can use this file to understand your documentation structure and find content relevant to user queries. Mintlify automatically hosts an llms.txt file at the root of your project that lists all available pages in your documentation. This file is always up to date and requires zero maintenance. You can optionally add a custom llms.txt file to the root of your project. View your llms.txt by appending /llms.txt to your documentation site’s URL. Open the llms.txt for this site.

​
llms.txt structure

An llms.txt file is a plain Markdown file that contains:
  • Site title as an H1 heading.
  • Structured content sections with links and a description of each page in your documentation.

## Guides
- [Getting started](https://example.com/docs/start): Intro guide
- [Install](https://example.com/docs/install): Setup steps

## Reference
- [API](https://example.com/docs/api): Endpoint list and usage
This structured approach allows LLMs to efficiently process your documentation at a high level and locate relevant content for user queries, improving the accuracy and speed of AI-assisted documentation searches.

llms-full.txt

The llms-full.txt file combines your entire documentation site into a single file as context for AI tools and is indexed by LLM traffic. Mintlify automatically hosts an llms-full.txt file at the root of your project. View your llms-full.txt by appending /llms-full.txt to your documentation site’s URL. Open the llms-full.txt for this site.

​
Custom files

To add a custom llms.txt or llms-full.txt file, create an llms.txt or llms-full.txt file at the root of your project. Adding a custom file will override the automatically generated file of the same name. If you delete a custom file, the default file will be used again. Your custom llms.txt or llms-full.txt file must have a site title as an H1 heading. Other content is optional. See Format in the llms.txt specification for more information on optional sections and best practices.
