1. Add the Scoped Registry
First, open Unity's Project Settings.
Under Package Manager, add a new Scoped Registry with the following information:
Name: coherence
URL: https://registry.npmjs.org
Scope(s): io.coherence.sdk
Enable Preview / Pre-release Packages: yes
Package Manager Advanced Settings
2. Install coherence
Now open the Window / Package Manager.
Select My Registries in the Packages dropdown.
Under coherence, click Install.
Alternative method: edit manifest.json manually
Refer to Unity's instructions on modifying your project manifest. 
Edit <project-path>/Packages/manifest.json.
Add an entry for the coherence sdk on the dependencies object, and for the scoped registry in the scopedRegistries array:
