# Attach a graph file to a Script Machine or State Machine
|
|
|
|
To use a Script Graph or State Graph file in your project, you must attach it to a Script Machine or State Machine.
|
|
|

A Script Machine or State Machine is a component. Components attach to GameObjects, and help define their behavior. For more information on components and GameObjects, see [Using components](https://docs.unity3d.com/2021.1/Documentation/Manual/UsingComponents.html) or [GameObjects](https://docs.unity3d.com/2021.1/Documentation/Manual/GameObjects.html) in the Unity User Manual.
