There is no installation, unzip the image and flash it to a SD card with you favorite flashing tool. If you logged in to the command line, you’re done.The base and server images have no GUI. Use the desktop image if you want a… desktop. You can install a Desktop Environment on the server image (I don’t like gnome, so that’s what I do) but with the base image that’s kind of the long way around, as it is as stripped down as possible.
I use dd on the command line in Linux myself. Enjoy!
