Launch

You can launch s&box in several ways:

• Launch through Steam directly
• Use a shortcut to sbox-dev.exe
• Open your .sbproj file directly

Building from Source (Optional)

The s&box engine is open source and MIT licensed. If you'd rather build it yourself, you can compile and run the engine from source.

Everything you need is in the sbox-public repository — clone it and follow the build steps in the README.

You only need this if you want to contribute to the engine or poke around its internals. For making games, installing through Steam is the recommended path.
