Markdown is a lightweight markup language created by John Gruber in 2004 that lets you write formatted documents using plain text. Its intuitive syntax—# for headings, ** for bold, - for lists—makes it easy for anyone to learn.
Markdown is used in GitHub README files, blog platforms (Jekyll, Hugo, Gatsby), Notion, Obsidian, Confluence, and many more. Developer communities like Stack Overflow and Reddit support Markdown syntax, and collaboration tools like Discord and Slack also support basic Markdown formatting.
HTML is a markup language rendered directly by web browsers using complex tag-based syntax. Markdown, on the other hand, is a plain-text format that is easy to read and write, and is automatically converted to HTML by a rendering engine. HTML is better for complex layouts and styling, while Markdown excels in writing convenience.
Markdown files typically use the .md extension, and .markdown is also recognized equivalently. GitHub automatically renders the README.md file in the repository root as the project introduction page. Most code editors (VS Code, Sublime Text, etc.) include built-in Markdown preview functionality.
The Markdown Preview tool is an online editor that converts Markdown text into HTML in real time. Write and preview Markdown directly in your browser with no software installation required.
Markdown syntax is simple and intuitive. Headings use # symbols to indicate levels. Bold and italic text use **bold** and *italic*. Links use the [link text](URL) format and images use . Code blocks are delimited by triple backticks, and blockquotes use a > symbol at the start of the line.
Markdown is especially widely used in software development. Code hosting platforms like GitHub, GitLab, and Bitbucket use Markdown for project documentation (README), issue trackers, and pull request descriptions. Modern note-taking apps such as Notion, Obsidian, and Bear also adopt Markdown-based editing.
The greatest advantage of Markdown is readability. Unlike HTML, the source text remains clean and easy to read without complex tag wrapping. Because it is a plain text format, it can be opened and edited in any text editor and integrates seamlessly with version control systems like Git.
