Created for readable source text, Markdown is widely used in documentation, README files, and conventions like llms.txt. Common patterns include # headings, - list items, and [label](url) links.
Because it is structured yet simple, it is convenient for both humans and tools that parse content for AI systems. See llms.txt.
