 ==== Find your Wireless Network ====
+\\
+To scan for wireless networks, use the following command:
+\\
+    sudo iwlist wlan0 scan
+\\
+If you have more than one SSID close by, then you could get quite a list. so you can use the following to work out what information you need.
+\\
+    sudo iwlist wlan0 scan |more
+    This will allow you to scroll through the pages of information you might get
+\\
+Or
+\\
+    sudo iwlist wlan0 scan |grep SSID
+    This will show just the SSIDs from the scan, meaning you can spot your SSDI more easily, for example:
+    ESSID:"Work"
+    ESSID:"Home"
+    ESSID:"Public"
+    ESSID:"Guests"
+    ESSID:"Samsung-Printer"

+==== Add WiFi details to Raspbian ====
+\\
+To add your details to Raspbian, use the following:
+\\
+    sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
+\\
+You will see a fairly empty file (assuming no one has edited this before)
+\\
+<file>
+country=GB
+ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
+update_config=1
+</file>
+\\
+At the end of this file, add the following lines.
+\\
+<file>
+network={
+    ssid="The_ESSID_from_earlier"
+    psk="Your_wifi_password"
+}
+So I might add:
+network={
+    ssid="Home"
+    psk="0123456789"
+}
+</file>
+\\
+Save the file, reboot the Pi and Voila!
