Specifically it supports:
- Inheritance
- Object instances
- Default/overriding variables
- States (categorized and uncategorized)
- Incredibly flexible layout engine
Gum exports to human-readable XML, and can be extended either using MEF or by modifying the source code directly.

Gum's runtimes are published to NuGet. Install the package for your platform. All packages share the same version number, so they stay in sync.

Shapes is the recommended way to draw rectangles, circles, and other primitives in Gum. On MonoGame and KNI it ships as a separate add-on package (install it alongside the runtime); on the other platforms it's built into the runtime.
Gum produces general-purpose XML, so it can be used in virtually any C# environment. Beyond the packaged runtimes listed above, integrations also exist for environments such as FlatRedBall, Meadow, Silk.NET, WPF, and Avalonia. For integration details — or for using GumCore to integrate with your own runtime — see the main documentation: https://docs.flatredball.com/gum/
