What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004 that converts plain text formatting to structurally valid HTML. It's designed to be as readable as possible in its raw form, making it the preferred format for documentation, README files, technical writing, and blogging.
GitHub Flavored Markdown (GFM) extends standard Markdown with tables, task lists, strikethrough text, fenced code blocks, and auto-linked URLs. It's the standard used across GitHub, GitLab, Stack Overflow, Reddit, Discord, and thousands of developer tools and platforms.
Whether you're writing documentation for your open-source project, drafting a blog post, creating lecture notes, or preparing a README file, a live-preview markdown editor helps you catch formatting issues instantly and export polished content ready for publishing.
