Import samples to your project
To import a Cinemachine sample to your project:
Open the Package manager window.
Find Cinemachine in the list of available packages, and select it.
In Package Manager's right pane, select the Samples tab.

Choose a sample set in the list and select Import to download and install the corresponding example Scenes and Assets.
For more details about the sample scenes included in each sample set, refer to the sample scene descriptions.
Unity places imported samples in your Project's Asset folder under
Assets/Samples/Cinemachine/<version number>.
To explore a specific Cinemachine use case or configuration, open the targeted Scene in the corresponding subfolder and enter Play mode to test the sample.
