 * In order to generate `Ros2ForUnity.unitypackage` please run `create_unity_package.ps1`. Please provide path to your Unity executable when prompted.
   * Asset can be found in `install\unity_package` directory
   * In case your Unity license has expired, the `create_unity_package.ps1` won't throw any errors but `Ros2ForUnity.unitypackage` won't be generated too.

-> If the Asset is built with `STANDALONE_BUILD` option set to `1` (the default), then nothing extra needs to be done.
+> If the Asset is built with `-standalone` flag (the default), then nothing extra needs to be done.
 Otherwise, you have to source your ros distribution before launching either Unity3D Editor or Application.
