+# Headless network setup
+
+If you are using a headless system and you aren't using an ethernet connection,
+you face a chicken-egg issue of how to connect the device to WiFi via `ssh` when
+the device isn't yet on the network.
+
+You can get around this by saving a file called `wp_supplicant.conf` to the
+`/boot` directory of the device. This specifies the SSID name and password and
+will be used to auto-connect when the device boots.
+
+For example:
+
+```
+country=GB
+ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
+update_config=1
+network={
+     ssid="SKYVL7XP"
+     scan_ssid=1
+     psk="WIFI_PASSWORD"
+     key_mgmt=WPA-PSK
+}
+```
