Use Linux in a web browser with Docker on a Synology NAS (Webtop)

Tutorial on how to fire up Webtop. This Docker container lets you use a Linux Desktop on your Synology NAS that you can access with a web browser. The installation is pretty quick, but I took a few minutes to show a little Linux Command Line fun. Or CLI if we wanna use slang for command line.
Note that it's a little limited. If you're using Linux tutorials out there, you might hit some speed bumps. It's not the same as running a virtual machine or a dedicated Linux machine. But it's very quick to set up.
Shout out to the LinuxServer.io team for having this container around. If you're in command line, type in "id". No quotes. Yeah, that's the same command line we run to get the PUID/GUID in Synology. That's basically all we're doing when we run that through the script manager thing in Synology.
