Got this one from ddg images but I think it was posted on reddit by someone.
Save the image to:
/.local/share/icons/
Save the modified .desktop file to:
/.local/share/applications/
This is mine, including the execution command modifier to make the window frame adwaita dark for gnome:

That's true about personal devices, but at least my server doesn't have nano installed. Though, in that case, you might manage with sshfs or something similiar. Also, for the 'Learn Vim' step, you only need to know the absolute basics, like entering input mode, saving & quitting.
