## What it is
Bluefin is an immutable, cloud-native Linux workstation operating system built on Fedora Silverblue and GNOME, distributed as OCI images via bootc. It provides a reliable, low-maintenance desktop experience with containerized developer tooling baked in.

## Use cases
- set up a reliable immutable linux workstation
- get a gnome desktop with developer tools preinstalled
- run a cloud-native desktop using bootc and oci images
- avoid maintaining a traditional linux distro on my laptop
- use a fedora-based desktop with containerized development environments

## When to choose
- you want a stable, low-maintenance linux desktop for development work
- you prefer immutable/atomic updates and container-based workflows
- you want a GNOME workstation with cloud-native tooling out of the box

## When to avoid
- you need a highly customizable traditional distro with package-level control
- you require a non-GNOME desktop environment or lightweight window manager
- you depend on software incompatible with immutable filesystems
