The Immerse SDK packages are provided via the [Package Manager](https://docs.unity3d.com/Manual/upm-ui.html ). After the SDK Installer has been run, a new Immerse registry will appear in the packages drop down menu. It is from here that you can select and add the required packages for your project.
The package manager can be opened from the Window menu.
