# Setup

* Download and install the VisionLib SDK in a new Unity project.
* Follow the instructions on our [documentation page](https://docs.echoar.xyz/unity/adding-ar-capabilities) to [set your API key](https://docs.echoar.xyz/unity/adding-ar-capabilities#3-set-you-api-key).
* Add the mini car model to the [console](https://docs.echoar.xyz/quickstart/add-a-3d-model) from the [Models](https://github.com/echoARxyz/Unity-ARFoundation-echoAR-demo-Living-Room-TV/tree/master/assets) folder.
* Overwrite the existing *echoAR/CustomBehavior.cs* script with the new [CustomBehavior](https://github.com/echoARxyz/Unity-ARFoundation-echoAR-demo-Living-Room-TV/blob/master/CustomBehavior.cs) file.
* Set up a Model Tracking scene using [VisionLib](https://visionlib.com/documentation/vl_unity_s_d_k_model_tracker_tutorial/)’s instructions, using *carEcho.vl and ModelTrackingScript.cs* in the Scripts folder instead of TutorialModelTracker.vl and Tutorial.cs.
* Tag the VLCamera Object as MainCamera in your scene.
* Print out and build VisionLib’s car target to test the model tracking.
