# Configuration {#configuration}

The extension can be configured via Site Settings and page properties.

## Site Settings {#configuration-site-settings}

After adding the Site Set to your site configuration (see [Activate the Site Set](https://docs.typo3.org/permalink/rtfirst/llms-txt:installation-site-set@1.0)),
you can configure the extension in **Site Management > Settings**.

-   **llmsTxt.baseUrl**

    -   *type:* string
    -   *Default:* (empty)

    Full URL of the website (e.g., `https://example.com`). This is used as
    the base URL in the generated llms.txt file. If empty, the site's base URL
    from the site configuration is used.

-   **llmsTxt.intro**

    -   *type:* text
    -   *Default:* (empty)

    Website description shown in the intro section of the llms.txt file.
    This text appears as a blockquote below the site title and helps AI
    crawlers understand the purpose of your website.

    Example:

    ```
    Your expert for tires, wheels, and automotive services since 1985.
    ```

-   **llmsTxt.excludePages**

    -   *type:* string
    -   *Default:* (empty)

    Comma-separated list of page UIDs to exclude from the llms.txt index.
    Use this for pages that should not appear in the LLM index, such as
    imprint, privacy policy, or internal pages.

    Example:

    ```
    42,56,123
    ```

-   **llmsTxt.includeHidden**

    -   *type:* boolean
    -   *Default:* false

    If enabled, hidden pages are also included in the llms.txt generation.
    This can be useful for staging environments or preview purposes.

-   **llmsTxt.apiKey**

    -   *type:* string
    -   *Default:* (empty)

    API key for protected access to `/llms.txt` and `.md` endpoints.
    If set, requests without a valid API key will receive a 401 Unauthorized
    response. Leave empty for public access.

    See [API Protection](https://docs.typo3.org/permalink/rtfirst/llms-txt:api-protection@1.0) for details on how to use API key protection.

## Page Properties {#configuration-page-properties}

Each page has an **LLM** tab in the page properties with the following fields:

-   **Exclude from llms.txt**

    -   *type:* checkbox
    -   *Default:* false

    If enabled, this page will not appear in the llms.txt index. The page
    is also excluded from the Markdown output.

-   **LLM Priority**

    -   *type:* number (slider)
    -   *Default:*
    -   *Range:* 0-100

    Higher values (0-100) cause the page to appear earlier in the llms.txt
    page list. Use this to highlight important pages for AI crawlers.

    **Recommendations:**

    -   **80-100**: Main landing pages, key services
    -   **50-70**: Important content pages
    -   **20-40**: Secondary pages
    -   **0-10**: Low-priority pages

-   **LLM Description**

    -   *type:* textarea
    -   *Default:* (empty)
    -   *Max length:* 500 characters

    Custom description for this page in the llms.txt index. If empty,
    the page's SEO meta description (from the SEO tab) is used as fallback.

    This description helps AI crawlers understand what the page is about.

-   **LLM Summary**

    -   *type:* textarea
    -   *Default:* (empty)
    -   *Max length:* 2000 characters

    Additional summary text shown as a blockquote in the llms.txt index.
    Use this for longer explanations that don't fit in the description.

-   **LLM Keywords**

    -   *type:* text input
    -   *Default:* (empty)
    -   *Max length:* 255 characters

    Comma-separated keywords/topics for this page. These appear in the
    llms.txt index and help AI crawlers categorize the page content.

    Example:

    ```
    tires, wheels, alignment, services
    ```

## robots.txt Configuration {#configuration-robots-txt}

To allow AI crawlers to discover and access your llms.txt file, add these
lines to your `public/robots.txt`:

```text
# Allow AI crawlers to access llms.txt
User-agent: GPTBot
Allow: /llms.txt

User-agent: Claude-Web
Allow: /llms.txt

User-agent: Anthropic-AI
Allow: /llms.txt

User-agent: Google-Extended
Allow: /llms.txt
```

> [!NOTE]
> The extension shows a notification in the TYPO3 Backend if your robots.txt
> does not contain a reference to llms.txt.

## HTML Header Link {#configuration-header-link}

The extension automatically adds a `<link>` tag to all HTML pages to help
AI crawlers discover the llms.txt file:

```html
<link rel="alternate" type="text/plain" href="/llms.txt" title="LLM Content Guide">
```

> [!NOTE]
> When API key protection is enabled, this header link is automatically
> hidden to prevent unauthorized crawlers from discovering the endpoint.
