About

Hypertext Markup Language (HTML) is a markup language used to create web pages and is the de facto standard for documents displayed in web browsers.

It defines the structure of web content using elements for text, links, images, forms, tables, and embedded media, organizes documents into a hierarchical DOM, and enables hyperlinking between pages, which is a fundamental mechanism of the World Wide Web.

HTML5 expanded HTML into a platform for web applications by introducing native audio and video elements, the canvas API for rendering graphics, Web Storage for client-side data persistence, Web Workers for background processing, the Geolocation API for location-based data, and WebSocket for real-time communication.

The llms.txt file is a proposed standard that provides structured content and instructions to guide large language models (LLMs) in understanding and summarizing a website's content.

It typically resides in the root directory and uses the Markdown format.

There is no evidence that any major LLM provider, such as OpenAI, Google, or Anthropic, currently uses or supports llms.txt.
