What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write using simple, readable plain-text syntax that converts to structurally valid HTML. Markdown has become the standard for README files, developer documentation, static-site content, and note-taking apps like Obsidian, Notion, and Bear. Its philosophy is that the source text should be as readable as the final output.
