+### How to run AIO on Synology DSM
+On Synology, there are two things different in comparison to Linux: instead of using `--volume /var/run/docker.sock:/var/run/docker.sock:ro`, you need to use `--volume /volume1/docker/docker.sock:/var/run/docker.sock:ro` to run it. You also need to add `-e DOCKER_SOCKET_PATH="/volume1/docker/docker.sock"`to the startup command. Apart from that it should work and behave the same like on Linux. Obviously the Synology Docker GUI will not work with that so you will need to either use SSH or create a user-defined script task in the task scheduler as the user 'root' in order to run the command.
+
+Also, you may be interested in adjusting Nextcloud's Datadir to store the files on the host system. See [this documentation](https://github.com/nextcloud/all-in-one#how-to-change-the-default-location-of-nextclouds-datadir) on how to do it.

+You'll also need to adjust Synology's firewall, see below:

+The Synology DSM is vulnerable to attacks with it's open ports and login interfaces, which is why a firewall setup is always recommended. If a firewall is activated it is necessary to have exceptions for ports 80,443, the subnet of the docker bridge which includes the nextcloud containers, your public static IP (if you don't use DDNS) and if applicable your NC-Talk ports 3478 TCP+UDP:

+
+If you have the NAS setup on your local network (which is most often the case) you will need to setup the Synology DNS to be able to access Nextcloud from your network via its domain. Also don't forget to add the new DNS to your DHCP server and your fixed IP settings:
