🌟 What is llms.txt?

The llms.txt file is an emerging web standard proposed to help Large Language Models (LLMs), AI agents, and custom search crawlers understand a website's purpose, core features, and primary documentation paths efficiently. By serving a concise, structured Markdown-based text file at the root directory (/llms.txt), you can significantly optimize how AI models consume and contextualize your project.
