Usage

This chapter explains how to access the LLM-optimized content.

Accessing llms.txt

The llms.txt index file is available at the root of your website, and below the base of every further language (see Multi-Language Access):

https://example.com/llms.txt
https://example.com/en/llms.txt

This file contains:

Website metadata (title, description, domain)
Page structure with descriptions and keywords
Instructions for accessing page content in Markdown format (if llmsTxt.enableMarkdown is enabled)

Example llms.txt Output

# My Website

> Your expert for quality products and services.

**Specification:** <https://llmstxt.org/>
**Domain:** https://example.com
**Language:** de
**Generated:** 2026-01-31 12:00:00

This site provides LLM-friendly Markdown output for all content pages.

**Markdown Format:** Append `.md` to a page URL to get plain Markdown with YAML frontmatter. Pages that only link to another page or URL are listed without a Markdown link.
- **Example:** `https://example.com/about.md`

## Languages

- [English](https://example.com/en/llms.txt): en

## Page Structure

- [Home](https://example.com/): Welcome to our website with all important information. [Markdown](https://example.com/index.html.md)
  - [About](https://example.com/about): Learn about our company history and values. [Markdown](https://example.com/about.md)
  - [Services](https://example.com/services): Professional services for your needs. Keywords: services, consulting, support. [Markdown](https://example.com/services.md)
  - [Contact](https://example.com/contact): Get in touch with us via phone or email. [Markdown](https://example.com/contact.md)
  - [Partner](https://example.com/partner): Our partner for logistics.

Each page is one line - [Title](url): notes as defined by llmstxt.org. The notes contain the description, summary and keywords of the page and the link to its Markdown version, so the file can be read by llms.txt parsers. Pages of type "Link" and "Shortcut" only point to another page or URL and have no content of their own, so they are listed without the Markdown link. The ## Languages section links to the llms.txt of the other languages; it is omitted on single-language sites.

With llmsTxt.enableMarkdown disabled, the Markdown hints (including the authentication hints) and the [Markdown](…) links are omitted.

Accessing Markdown Content

Append .md to any page URL to get the content as clean Markdown with YAML frontmatter.

https://example.com/about.md

Pages of type "Link" or "Shortcut" have no content of their own. Their .md URL behaves like the page URL: TYPO3 redirects to the target, or shows the target page for a "Link" to a page in TYPO3 14.

Note

The Markdown output is enabled by default. It can be turned off per site with llmsTxt.enableMarkdown, .md URLs then return a regular 404.

Example Markdown Output

---
title: "About Us"
description: "Learn about our company history and values."
language: en
date: 2024-06-15
lastmod: 2026-01-31
canonical: "/about"
format: markdown
generator: "TYPO3 LLMs.txt Extension"
---

# About Us

> Learn about our company history and values.

## Our History

Our company was founded in 1985...

## Our Values

- Quality and reliability
- Fair and transparent prices
- Personal consultation

The YAML frontmatter contains:

title: Page title
description: Page description (from LLM or SEO settings)
language: ISO language code
date: Page creation date (from TYPO3 crdate)
lastmod: Last modification date (most recent change across page and content elements); omitted if same as date
canonical: Canonical URL path
format: Output format (always "markdown")
generator: Extension identifier

Accessing the Root Page

For the root/home page, use:

https://example.com/index.html.md

Or simply:

https://example.com/.md

Multi-Language Access

Every enabled language of a site has its own llms.txt below its base:

# Default language
https://example.com/llms.txt

# English (base /en/)
https://example.com/en/llms.txt

# Language with its own domain
https://example.co.uk/llms.txt

Each file lists the pages in its language, with translated titles, descriptions and URLs. With fallbackType: strict, untranslated pages are left out. The ## Languages section of each file links to the llms.txt of the other languages. A language without pages has no llms.txt (404).

The intro comes from the field llms.txt Intro of the language, or for the default language from llmsTxt.intro. The API key (llmsTxt.apiKey) protects the llms.txt of every language.

Access page content in different languages using the language URL prefix with the .md suffix:

# German (default language)
https://example.com/ueber-uns.md

# English
https://example.com/en/about.md

# French
https://example.com/fr/a-propos.md

The extension automatically:

Detects the language from the URL prefix
Loads the translated page content
Sets the correct language in the YAML frontmatter

Caching

The extension uses smart caching for optimal performance:

llms.txt: Cached and regenerated when TYPO3 cache is cleared or the llmsTxt.* site settings change
Markdown output: Cached for 24 hours per page/language combination

To force regeneration:

vendor/bin/typo3 cache:flush

Or in DDEV:

ddev typo3 cache:flush

Content Filtering

The Markdown output is automatically cleaned for better LLM consumption:

Removed elements:

Scripts and styles
Navigation and footer elements
Sidebar content
Bootstrap accessibility spans (visually-hidden)
Empty anchor tags (<a id="c1"></a>)

Preserved elements:

Main content text
Headings and structure
Lists and tables
Images (converted to Markdown syntax)
Links (converted to absolute URLs)
