What is llms.txt?
The llms.txt file is a proposed standard for providing guidance to AI agents and large language models about how to interact with your website.
Similar to how robots.txt guides search engine crawlers, llms.txt helps AI systems understand your content, attribution preferences, and how to cite your information.
