PreviewMarkdown provides QuickLook file previews and file icon thumbnails for documents created using the popular markdown markup format.

The app provides two app extensions: Previewer and Thumbnailer, which can be viewed and managed in macOS’ System Preferences > Extensions. The app itself is simply a container for these extensions.

You must run the app first to gain these benefits.
