### Configure your Auth0 credentials
-First, you need to put your `AUTH0_DOMAIN` (example.auth0.com), your `AUTH0_CLIENT_ID` and your `AUTH0_CLIENT_SECRET` on the `auth0-variables.js` file . You can find this information in the Application Settings on your Auth0.com dashboard.
+First, you need to set the ClientSecret, ClientId and Domain for your Auth0 app as environment variables with the following names respectively: `AUTH0_CLIENT_SECRET`, `AUTH0_CLIENT_ID` and `AUTH0_DOMAIN`. You can find this information in your Auth0 Dashboard.
+
+So, create a file named `.env` in the directory and set the values like the following:
+
+````bash
+# .env file
+AUTH0_CLIENT_SECRET=myCoolSecret
+AUTH0_CLIENT_ID=myCoolClientId
+AUTH0_DOMAIN=myCoolDomain
+````
