====== Connect Raspberry Pi to Wifi ======
It is fairly self explanatory to do it through the UI if there is one but to do it through the terminal all you have to do is :

  * sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
  * # Ensure it looks like
  * <code>country=GB
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="Errigal_WiFi"
    psk="PASSWORD"
}
</code>
  * save and exit
  * Reboot and it should connect
  * If having issues ensure your 
  * sudo nano /etc/network/interfaces
  * looks like
  * <code># interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
