To make guerillaClock more mobile and versatile, additional wireless networks can be added beyond that which is configured within sudo raspi-config.  

Add Additional Wireless Networks

1. Type sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
2. Look within the wpa_supplicant.conf file for a "network" section that looks like this:

   network={
        ssid="SSID_added_during_raspi-config"
        psk="password_for_SSID"
   }

3. Add additional "network" sections for each wireless network to which guerillaClock will connect
   

   network={
        ssid="SSID_added_during_raspi-config"
        psk="password_for_SSID"
   }
   
   network={
        ssid="freewifi"
        psk="topsecretpass"
   }
   
   network={
        ssid="myHotSpot"
        psk="passwordDefintedByHotSpot"
   }
