-Contributing to MRTK3 is easy. We recommend using the `MRTKDevTemplate` Unity project as a convenient development testbed, as it already includes all the MRTK3 packages as local on-disk dependencies. [For more information, see the documentation on the MRTKDevTemplate project for more details on sample scenes and local on-disk dependencies.](getting-started/exploring-features/mrtk3-sample-scenes.md)
