Unity Package Manager

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:
