The following instructions will work anytime, you don’t necessarily have to follow them for the first boot – this is just a very convenient way to get your Raspberry Pi onto a network without using any plug-in peripherals like a keyboard, mouse or monitor.
What is “headless,” anyway?
A computer setup without a monitor is said to be running headless. You might want to do this if you’re installing your Pi into some project, or want to keep power-usage and cost minimal. This kind of setup is what the Pi Zero W was built for. The idea is that you can still access your Pi’s terminal interface over your network using a protocol called SSH.
All we need to do is get our Pi set up with the right WiFi credentials and we’ll be able to remotely access it through a terminal program, as if we were using the terminal Pi’s own desktop. What’s more, we’ll get our Pi connected to WiFi without ever having to plug in a monitor, keyboard or mouse to configure it.Read More
