+Once you start deploying to a cloud, you may end up having to publicly expose your backend and frontend to the internet. In this case you will need to disable the admin mode on the deployed components.
+
+Just deploy with the `ADMIN_MODE` env var as disabled. This could be in your Dockerfile, or any other deployment config.
+```shell
+ADMIN_MODE=0
+```
