+# Cymbal Shops Branding
+
+By default, when you deploy this sample app, the "Online Boutique" branding (logo and wording) will be used.
+But you may want to use Google Cloud's fictitious company, _Cymbal Shops_, instead.
+
+To use "Cymbal Shops" branding, set the `CYMBAL_LOGO` environment variable to `"true"` in the the Kubernetes manifest (`.yaml`) for the `frontend` Deployment.
+
+```
