First thing to remember is that this is a text interface so no mouse. You move between the different items with the arrow keys and select them by hitting enter. If you need to select a check box on one of the later screens, you hit space, and when you’re done, you move between the list of actions and the buttons at the bottom by pressing the “tab” key. raspi-config (Click to enlarge) The first thing to do is check that we have the latest version of raspi-config (if your pi doesn’t currently have anyway of connecting to the internet, you can skip this).
