 ### Notes
-- This is not working on Docker Desktop since it needs `network_mode: host` in order to work correctly.

 - After adding and starting the container, you can directly visit http://ip.address.of.server:8096/ and access your new Jellyfin instance!
-- The data of Jellyfin will be automatically included in AIOs backup solution!
-- See https://github.com/nextcloud/all-in-one/tree/main/community-containers#community-containers how to add it to the AIO stack
+- In order to access your Jellyfin outside the local network, you have to set up your own reverse proxy. You can set up a reverse proxy following [these instructions](https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md) and [Jellyfin's networking documentation](https://jellyfin.org/docs/general/networking/#running-jellyfin-behind-a-reverse-proxy), OR use the [Caddy](https://github.com/nextcloud/all-in-one/tree/main/community-containers/caddy) community container that will automatically configure `media.$NC_DOMAIN` to redirect to your Jellyfin.
+- ⚠️ After the initial start, Jellyfin shows a configuration page to set up the root password, etc. **Be careful to initialize your Jellyfin before adding the DNS record.**

 - This is not working on arm64 since Plex does only provide x64 docker images.
 - This is not working on Docker Desktop since it needs `network_mode: host` in order to work correctly.
 - If you have a firewall like ufw configured, you might need to open all Plex ports in there first in order to make it work. Especially port 32400 is important!
