## What it is
A macOS Quick Look extension that renders syntax-highlighted previews of source code files in Finder, built on the Highlight library. It ships as a standalone app with a settings UI and CLI, supporting macOS 10.15 and later.

## Use cases
- preview source code files in Finder with syntax highlighting
- quickly view code files without opening an editor
- customize Quick Look themes and colors for code previews
- add support for custom file formats in macOS Quick Look
- highlight source files on macOS Catalina and later

## When to choose
- you want fast, in-Finder previews of source code on macOS
- you need configurable highlighting themes and broad file-format support
- you prefer a native Quick Look extension over opening files in an IDE

## When to avoid
- you are on Linux or Windows, since it is macOS-only
- you need full editing or IDE features rather than read-only previews
- you require macOS versions older than 10.15 Catalina
