+        GitHub requires npm authentication to fetch packages. To authenticate with the GitHub NPM registry, you need to create a `.npmrc` file in your project directory with
+        the following content:
+
+        ```bash
+        //npm.pkg.github.com/:_authToken=TOKEN
+        @chroma-core:registry=https://npm.pkg.github.com
+        ```
+
+        Replace `TOKEN` with your GitHub token. More info can be found [here](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-npm-registry#authenticating-with-a-personal-access-token).
