+## Supported Environments
+
+We support Node.js 6.0 and higher. Please note that the Admin SDK should only
+be used in server-side/back-end environments controlled by the app developer.
+This includes most server and serverless platforms (both on-premise and in
+the cloud). It is not recommended to use the Admin SDK in client-side
+environments.
