+
+This Docker Compose file assumes you have a reverse proxy (like Nginx) in a Docker container on another Docker network. If you are not using a reverse proxy or do not wish to use the Docker network to connect the reverse proxy, you can set the `frontend` network's `external` property to be `false` in [docker-compose.yaml](docker-compose.yaml). You may also need to expose the HTTP port (80) on the `nextcloud` service.
