Live preview of Markdown rendering
Markdown is the most popular lightweight markup language among developers, used for documentation, READMEs, blogs, and technical notes. A Markdown preview tool lets you see the rendered output in real time as you edit, without needing to push to GitHub or spin up a local server to check your formatting.
