That means that in the case of BW, all your imported data, long random passwords that you have defined are gone! Now that you have understood the importance of this let's configure an outside volume that will keep your data safe from this scenario. As a result, all your work will be reset and gone. This means that after you restart your container (reboot, NAS update, Docker update, docker image update) it will reset itself to initial settings. If you start working with your container, all information, configuration, data etc, are sandboxed inside the container. Read up on those so that I don't start messing with this tutorial too much, but in short, it means this. Now, this is the most important thing that needs to be done when working with containers. I use Heimdall for all my docker URL needs so this option is OFF (again, you can use it if you choose to do so). The desktop in this context is DSM desktop, not your computer desktop.

Regarding shortcuts on the desktop, personally, I don't use it. Ofc this is an optional setting but still. The Auto-restart feature is nice to have ON in case you need to reboot your nas or Docker for that matter and want all your containers booting automatically.
