Hi @x11, thank you for stopping by the Magic Leap 2 forum. You can learn more about our [Controller here](https://developer-docs.magicleap.cloud/docs/guides/unity/input/controller/unity-controller-overview)

We have an [example Controller project here](https://developer-docs.magicleap.cloud/docs/guides/unity/sdk-example-scenes/sdk-controller-scene)

Please note our documentation does assume familiarity with Unity or C++ to work with Magic Leap APIs.
