Installation

Installation via Composer (Recommended)

Install the extension via Composer:

composer require rtfirst/llms-txt

Then activate the extension and clear the cache:

vendor/bin/typo3 extension:setup
vendor/bin/typo3 cache:flush

For DDEV environments:

ddev composer require rtfirst/llms-txt
ddev typo3 extension:setup
ddev typo3 cache:flush

See also Installing extensions in the TYPO3 Getting Started documentation.

Installation in Classic Mode

Download the extension from the TYPO3 Extension Repository (TER) or download rt_llms_txt_<version>.zip from the assets of a GitHub release.
Install the extension via the Extension Manager in the TYPO3 Backend.
Clear all caches.

Note

The extension requires the Composer package league/html-to-markdown (MIT license). In classic mode no Composer packages are installed, so the TER package and the zip file of the GitHub release ship it in Resources/Private/Php/ComposerVendor/, including its license file.

The "Source code" archives of a GitHub release and a plain Git checkout do not contain this package and do not work in classic mode.

Activate the Site Set

After installation, you need to add the Site Set to your site configuration:

Go to Site Management > Sites in the TYPO3 Backend.
Edit your site configuration.
Go to the Sets tab.
Add the set LLMs.txt Generator (rtfirst/llms-txt).
Save and clear all caches.

Adding the LLMs.txt Generator site set — Add the LLMs.txt Generator site set to your site configuration.

Verify Installation

After installation, verify that everything works:

Access https://your-site.com/llms.txt - You should see the generated llms.txt content.
Access any page with .md suffix, e.g., https://your-site.com/about.md - You should see Markdown content with YAML frontmatter.
Check the page properties of any page - You should see a new LLM tab.

Tip

If you get a 404 error, make sure you've added the Site Set and cleared all caches.
