The plugin integrates with macOS Quick Look to render plain‑text files that lack a file extension, allowing them to be previewed directly from Finder. It supports common source‑code and documentation files such as README, INSTALL, CHANGELOG, Makefile, Rakefile, and CapFile, which the default Quick Look handlers ignore. By enabling quick visual access to these files, the tool streamlines the workflow of developers and anyone who frequently inspects raw text without opening a dedicated editor.

Installation is straightforward for macOS 10.5 and later; the compiled bundle is a few kilobytes in size and can be placed in the system’s Quick Look plugin directory. Once installed, selecting a supported file and pressing the space bar triggers the preview, displaying the file’s contents with standard text formatting.

The project is maintained as an open‑source repository on GitHub, where users can download the latest build, view the source code, or contribute improvements. It has been stable since its initial release in 2008 and is distributed under a proprietary rights notice by its author.
