llms.txt

The .llms.txt feature allows your documentation site to expose a structured, machine-readable index that helps large language models (LLMs) discover and understand your content more efficiently.

What Is .llms.txt?

.llms.txt is a plain-text file that provides a structured summary of your documentation, including:

• The title and description of each section
• Direct links to the corresponding Markdown (.md) source files
• A hierarchical overview of your content structure

This allows AI tools, developer assistants, and LLM-powered integrations to index your documentation accurately - without needing to crawl or parse your full rendered HTML site.

How It Works

Theneo generates your .llms.txt file automatically using the SEO management data you have already configured for each page in your documentation. No additional setup is required for content that already has SEO fields filled in.

The file is built from the following existing fields:

Each entry in the .llms.txt file maps one documentation page to its title, a short description, and the direct link to its Markdown source file.

File Format

The generated .llms.txt file follows the standard format below:

 
# <Site Title>

> <Site-level description>

## <Section Name>

- [<Page Title>](<link-to-.md-file>): <Page description>
- [<Page Title>](<link-to-.md-file>): <Page description>

## <Section Name>

- [<Page Title>](<link-to-.md-file>): <Page description>

Managing SEO Data for Better Coverage

Since .llms.txt is generated from your existing SEO fields, the quality of your index depends on how thoroughly those fields are filled in. To ensure complete and accurate coverage:

• Title: Keep titles concise and descriptive. Avoid generic labels like "Overview" when a more specific title such as "Authentication Overview" is more informative.
• Description: Write descriptions that summarize what the page covers in one to two sentences. This text appears directly in the .llms.txt file and is what LLMs will use to understand the page's purpose.
• Slug: Use clean, readable slugs that reflect the page hierarchy (e.g., /guides/authentication rather than /page-42).

To review or update SEO data for a page:

1. From the project dashboard, navigate to SEO Management.
2. Edit the Title, Description, and Slug fields as needed.
3. Click Save Changes.

Verifying Your .llms.txt File

You can verify the file is live and correctly formatted by visiting your documentation URL directly in a browser or using a tool such as curl:

 
curl https://app.theneo.io/theneo/quickstart/llms.txt

Check the following:

• All major sections of your documentation are represented.
• Each entry includes a title, a valid link to a .md file, and a description.
• The file is accessible without authentication (it must be publicly reachable to be useful to external LLM systems).
