## What it is
umu-launcher is a unified launcher for running Windows games on Linux using Proton outside of Steam. It replicates Valve's Steam Runtime Tools and containerization setup so Proton can launch games without the Steam client.

## Use cases
- run Windows games on Linux without Steam
- launch Proton games from a non-Steam launcher
- use Proton with Lutris or Heroic
- set up a Steam Linux Runtime environment outside Steam
- run Proton from the command line

## When to choose
- you want to play Windows games on Linux using Proton without the Steam client
- you use third-party launchers like Lutris or Heroic and want Proton compatibility
- you need a maintained, community-driven replacement for Steam's runtime tooling

## When to avoid
- you only play games through Steam, which already handles Proton natively
- you need a full graphical game library manager rather than a launch mechanism
- you are on Windows or macOS, as this targets Linux only
