+Then edit the `config/production.yaml` file according to your webserver and database configuration. In particular:
+ * `webserver`: Reverse proxy public information
+ * `secrets`: Secret strings you must generate manually (PeerTube version >= 5.0)
+ * `database`: PostgreSQL settings
+ * `redis`: Redis settings
+ * `smtp`: If you want to use emails
+ * `admin.email`: To correctly fill `root` user email

 Keys defined in `config/production.yaml` will override keys defined in `config/default.yaml`.
 
 **PeerTube does not support webserver host change**. Even though [PeerTube CLI can help you to switch hostname](https://docs.joinpeertube.org/maintain-tools?id=update-hostjs) there's no official support for that since it is a risky operation that might result in unforeseen errors.
