This guide outlines the process of creating and hosting llms.txt files, which are plain Markdown files that provide a concise summary of a website's most important content to aid AI tools in indexing. It emphasizes the benefits of using Mintlify's free generator tool to create starter templates and discusses hosting requirements, ensuring the files are placed at the root of the website for easy access by large language models (LLMs). The llms.txt format includes a title, blockquote summary, and organized sections with links to key content areas, making it particularly useful for product documentation to ensure AI-generated answers are accurate and contextual. The guide also highlights that Mintlify automatically generates and hosts these files, allowing companies to make their content AI-ready seamlessly.
