QLMarkdown is a simple QuickLook generator for Markdown files. It renders a preview of the selected Markdown file using Discount -- a C implementation of John Gruber's script.

To update to the latest version of discount run ./discount-config/

For more information on Markdown see


Simply copy QLMarkdown.qlgenerator to ~/Library/QuickLook or /Library/QuickLook.

If the newly installed plugin is not picked up instantly, you run qlmanage -r in a terminal to refresh.

To uninstall, drag QLMarkdown into the trash.

Another method, if you have Homebrew Cask installed:

$ brew update
$ brew cask install qlmarkdown

To uninstall

$ brew cask uninstall qlmarkdown

Note: Quick Look doesn't allow selecting text. If you want to select the text in the markdown preview, you will need to enable text selection in Quick Look by running the following in Terminal:

defaults write QLEnableTextSelection -bool TRUE; killall Finder
