Optimizely Configured Commerce automatically generates an `llms.txt` file within your site's Spire CMS. This file functions similarly to [robots.txt](docId\:WPz_4kXG6AcbIXQn-OQTy) and serves as a configuration point for integrating with AI features, letting you specify which content should be made available to large language models (LLMs). By default, the generated `llms.txt` file is empty, meaning no content is exposed to LLMs unless you explicitly configure it.

You should work with [Mark (Optimizely Agent Platform)](docId\:IzAAN1fw7whD1HB4iODAB) for maximum benefits and support. When you point Mark to your website, Mark can provide suggested copy based on the requirements found on  [`https://llmstxt.org/`](https://llmstxt.org/) using prompts like *Based on the requirements found on* [https://llmstxt.org/,](https://llmstxt.org/) *create a llms.txt file for the site \[paste domain of website here]*.

## Best practices

An `llms.txt` file acts as a concise, expert guide for LLMs, helping them understand your website's most important content quickly. 

Keep these things in mind:

- **Start with a clear title and summary** – Begin each file with a main heading (`# Site Name`) and a brief, one-sentence summary in a blockquote (`> Summary...`) to give the LLM immediate context.
- **Be a curator, not a collector** – Think of this file as a curated list of your site's "greatest hits." Instead of listing every page like a sitemap, select only the most critical resources that a user (or LLM) would need to get started.
- **Prioritize clarity and brevity** – Use simple language and keep descriptions short and to the point. The goal is to provide high-value information that can be processed quickly, without the clutter of complex HTML and scripts.
- **Use descriptive links** – Describe its purpose when you add a link to give the LLM context about why it is important.
  - **Good** –  `- [Quickstart Guide](url): A 5-minute tutorial for new users`
  - **Less good** – `– [Quickstart](url)`
- **Use the** `## Optional` **section strategically** – Place links to secondary or less critical information under an `## Optional` heading. This lets an LLM focus on the core content first and access deeper information if needed.
- **Link to LLM-friendly content** – Point your links to clean, Markdown-formatted versions of your pages (ending in `.html.md`) when possible. This makes the content easier for an LLM to read and understand.
