What this tool does
Preview a lightweight subset of Markdown while drafting text.
How to use it
Type headings, paragraphs and supported inline markup; compare the source with the preview.
Worked example
# Release notes produces a level-one heading reading Release notes.
Limitations and checks
This is a lightweight renderer, not full CommonMark or GitHub Markdown. Check tables, nesting and code blocks in the destination renderer before publishing.
