 To authenticate to your private registry, you'll need to store your npm authentication token as a secret. For example, create a repository secret called `NPM_TOKEN`. For more information, see "[Creating and using encrypted secrets](/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets)."
 
-In the example below, the secret `NPM_TOKEN` stores the npm authentication token. The `setup-node` action configures the *.npmrc* file to read the npm authentication token from the `NODE_AUTH_TOKEN` environment variable. When using the `setup-node` action to create an *.npmrc* file, you must set the `NPM_AUTH_TOKEN` environment variable with the secret that contains your npm authentication token.

 Before installing dependencies, use the `setup-node` action to create the *.npmrc* file. The action has two input parameters. The `node-version` parameter sets the Node.js version, and the `registry-url` parameter sets the default registry. If your package registry uses scopes, you must use the `scope` parameter. For more information, see [`npm-scope`](https://docs.npmjs.com/misc/scope).
