# Introduction {#introduction}

## What does this extension do? {#what-does-this-extension-do}

The LLMS TXT Generator gives Large Language Models (LLMs) and AI tools a
compact, machine-readable view of a TYPO3 site, following the
[llmstxt.org specification](https://llmstxt.org/).

It provides two outputs:

1.  **llms.txt** \- a Markdown index of the site: its title, a short summary,
    optional metadata and a structured list of links to the site's pages.
1.  **Markdown pages** \- every listed page can be fetched as plain Markdown by
    appending `.md` to its URL, without navigation, header or footer.

## Key features {#key-features}

-   **llms.txt generation** at `/llms.txt` and `/.well-known/llms.txt`
-   **Page tree listing** with configurable depth and page type exclusion
-   **Markdown version of every page** through TYPO3's regular rendering, so
    all content elements and column positions are included
-   **Per-site configuration** of title, summary, topics, contact address and
    additional content
-   **Respects page visibility**: hidden, access-restricted, "hide in menu" and
    "no index" pages are not listed
-   **Optional caching** of the generated `llms.txt`
-   **CLI export** of pages as Markdown files

## What is llms.txt? {#what-is-llms-txt}

`llms.txt` is a proposed convention for a Markdown file at the root of a
website that tells language models what the site is about and where its most
useful content is. Language models have limited context windows and struggle
with full HTML pages; a curated index with links to clean Markdown versions
lets them find and read the relevant content directly.

`llms.txt` is **not** an access control mechanism. It does not grant or deny
permission to crawl or train on your content; use `robots.txt` and your
server configuration for that.

## Requirements {#requirements}

-   TYPO3 13.4 LTS or 14.3 LTS
-   PHP 8.2, 8.3 or 8.4
-   The TYPO3 system extension `seo` (installed automatically with Composer)
