Setting up Wi-Fi on the Raspberry Pi and enabling SSH

Now you've seen what you get with a headless system, let's modify the SD card so the Raspberry Pi starts up ready to use as a headless device. We need to set up Wi-Fi first:

1. Remove and reinsert the MicroSD card we made earlier into your computer so that the computer can recognize the new state of the drive.
2. Now you will see the card shows up as two disk drives. One of the drives is called boot; Windows will ask whether you want to format the other drive. Click Cancel when Windows asks you. This part of the SD card holds a Linux-specific filesystem that Windows cannot read.
3. Now, in boot, create two files as follows. I suggest using an editor such as VSCode for plain text files, seeing file extensions, and making empty files:
   • ssh: An empty file with no extension.
   • wpa_supplicant.conf: This file contains your Wi-Fi network configuration as shown here:

     country=GB
     update_config=1
     ctrl_interface=/var/run/wpa_supplicant...
