When you install the coherence Unity Package, all the services for the SDK are installed in the background as well.
You will then see this package in the Package Manager under "My Registries".
The coherence SDK has some dependencies on other Unity packages you can see in the image above. If you're already using these in your project, you might have to adjust their version number (Unity will tell you about this).
When you successfully install the coherence SDK you'll get this quickstart winodow pop-up and you'll be good to go.
