They can't process complex HTML pages well. Simplifying these pages into plain text helps LLMs access clear, expert-level information. This is crucial for applications like development environments, where quick access to documentation and APIs is needed. ## Optional - [Standardization of llms.txt](https://llmstxt.org): A proposal to standardize the use of an /llms.txt file to assist LLMs in using a website effectively.
