How to Use Markdown Preview

  2. 2

    Enable GitHub Flavored Markdown

    The preview supports GFM extensions: strikethrough (~~text~~), tables (| header | data |), task lists (- [ ] todo), and code fence syntax highlighting.

  3. 3

    Preview formatting in real-time

    The right pane updates instantly as you type. Check that headings, code blocks, and links render correctly before publishing or sharing.

    Copy rendered HTML

    Some versions export rendered HTML or allow copy-pasting the preview directly into platforms that accept rich text (Notion, Medium, etc.). Use for documentation and blog posts.
