The `llms.txt` file is an [emerging convention](https://llmstxt.org/) used to
provide a machine-readable summary of a website's content, specifically designed
for LLMs and AI agents.

Without this file, agents may spend more time crawling the site to understand
its high-level structure and primary content.

## How the llms.txt audit works

Lighthouse flags the pages if a server error occurs when attempting to retrieve
the `llms.txt` file. If the file is not provided by the server (resulting in a
404), the audit is marked as Not Applicable (N/A), as providing the file is
optional at the moment.

## How to fix

Create an `llms.txt` file and place it in the root directory of your website
(for example, `https://example.com/llms.txt`). The file should follow the [llms.txt
specification](https://llmstxt.org/) and provide a concise Markdown summary of
your site's purpose and key links.
