## What it is
ChimeraOS is a Linux distribution that turns any PC into a gaming console using Steam Big Picture mode. It provides a fully controller-compatible couch gaming experience with automatic background updates.

## Use cases
- turn an old PC into a gaming console
- couch gaming with controller-only interface
- set up a Steam Machine-like living room PC
- automatic updates for a dedicated gaming OS
- play Steam games on a TV from a Linux box

## When to choose
- you want a console-like Steam Big Picture experience on a PC
- you want a minimal OS dedicated to gaming with automatic updates
- you want full controller navigation from boot

## When to avoid
- you need a general-purpose desktop Linux with a traditional window manager
- you primarily play games outside Steam with no controller support
