# Frequently Asked Questions (FAQ) {#faq}

## General Questions {#faq-general}

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

`llms.txt` is an emerging standard for providing AI and Large Language Model
(LLM) crawlers with structured information about a website. It helps AI systems
understand your website's content and structure. See the
[llmstxt.org specification](https://llmstxt.org/) for details.

### Why should I use this extension? {#faq-why-use}

-   **Better AI understanding** of your website content
-   **Structured access** for chatbots and RAG systems
-   **Clean Markdown output** without navigation, scripts, or styling
-   **Multi-language support** out of the box
-   **Optional protection** with API keys

## Installation Questions {#faq-installation}

### I get a 404 error when accessing /llms.txt {#faq-404-error}

Make sure you have:

1.  Added the **Site Set** to your site configuration
1.  Cleared all caches: `vendor/bin/typo3 cache:flush`

See [Activate the Site Set](https://docs.typo3.org/permalink/rtfirst/llms-txt:installation-site-set@1.0) for details.

### The LLM tab doesn't appear in page properties {#faq-no-llm-tab}

1.  Verify the extension is installed: `vendor/bin/typo3 extension:list`
1.  Clear the system cache
1.  Log out and log back into the TYPO3 Backend

## Configuration Questions {#faq-configuration}

### How do I exclude specific pages? {#faq-exclude-pages}

You have two options:

1.  **Site Settings**: Add page UIDs to `llmsTxt.excludePages` (comma-separated)
1.  **Per Page**: Check "Exclude from llms.txt" in the page's LLM tab

### How does the priority setting work? {#faq-priority}

Pages with higher priority values (0-100) appear earlier in the llms.txt
page list. Use this to highlight important pages for AI crawlers:

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

### Can I include hidden pages? {#faq-hidden-pages}

Yes, enable `llmsTxt.includeHidden` in the Site Settings. This is useful
for staging environments.

## Usage Questions {#faq-usage}

### How do I access the root page as Markdown? {#faq-root-page-md}

Use `/index.html.md` or `/.md`:

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

### How do I access translated pages? {#faq-language-access}

Use the language prefix with the `.md` suffix:

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

# German
https://example.com/de/ueber-uns.md
```

### How do I refresh the cached content? {#faq-cache-refresh}

Clear the TYPO3 cache:

```bash
vendor/bin/typo3 cache:flush
```

Or in DDEV:

```bash
ddev typo3 cache:flush
```

## API Protection Questions {#faq-api-protection}

### Which HTTP header should I use for the API key? {#faq-api-key-header}

Use `X-LLM-API-Key`:

```bash
curl -H "X-LLM-API-Key: your-key" https://example.com/llms.txt
```

### Can I use a query parameter instead? {#faq-api-key-query}

Yes, use `api_key`:

```text
https://example.com/llms.txt?api_key=your-key
```

However, HTTP headers are recommended for security reasons.

## Troubleshooting {#faq-troubleshooting}

### The Markdown output is empty {#faq-empty-markdown}

-   Check if the page has content elements
-   Verify the page is not excluded from llms.txt
-   Clear all caches

### Content shows in wrong language {#faq-wrong-language}

-   Verify your site language configuration
-   Check if translations exist for the page
-   Use the correct language prefix in the URL

### Some content elements are missing {#faq-missing-content}

The extension filters out:

-   Navigation elements
-   Footer content
-   Scripts and styles
-   Empty elements

If a specific content type is missing, you may need to create a custom
converter. See [Creating Custom Converters](https://docs.typo3.org/permalink/rtfirst/llms-txt:developer-custom-converter@1.0).
