## Project Overview
Aurora is a "delightful KDE desktop experience for end-users that are looking for reliability and developers for the most-hassle free setup" built on Universal Blue's framework. It creates an immutable, container-based Linux desktop with zero maintenance included.
The repository structure follows Universal Blue conventions, using container-based builds to create a polished KDE desktop experience with pre-configured development tools, media codecs, and productivity software.
