How does one start a node on an ARM computer these days?

I haven’t visit this place in a long time, so I checked to see what has changed and well… what happened to installing an executable node app?

Why is it heading into the direction of X86 computers? Those are desktops. Don’t you want nodes to be run by SBCs? I thought that was the whole idea to have small dedicated servers for autonomi. That would be the most logical.

And does one really need 8GB of RAM? Is the node that RAM intensive?
