Look for "Markdown Previewer" and "Markdown Thumbnailer" in your system settings.

Enable or disable these at any time under System Settings > Extensions > Quick Look .

Added a direct link within the app to PreviewJson, a sibling tool for JSON file visualization.

Press Space on a Markdown file in Finder to view a rendered version instead of raw text.

To activate the functionality, you must run the host app at least once after installation to register the extensions with macOS.
