PreviewMarkdown

PreviewMarkdown provides QuickLook file previews and file icon thumbnails for documents created using the popular markdown markup format. The app provides two app extensions: Markdown Previewer and Markdown 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. PreviewMarkdown supports the following markdown features: *italics* or _italics_ **bold** or __bold__ ~~Strikethroughs~~ `code` # Header 1 or Header 1 ==== ## Header 2 or Header 2 --- ### Header 3 #### Header 4 ##### Header 5 ##### ###### Header 6 ###### Indented code blocks (spaces or tabs) [Links](https://smittytone.net/previewmarkdown) [Referenced Links][1] [1]: https://smittytone.net/previewmarkdown > Blockquotes - Bullets - Lists - Including indented lists (spaces or tabs) - Up to any number of levels (spaces or tabs) 1.
