+On the LCD the four connections will be labelled something like:
+\\
+    LCD          R-Pi
+    GND (Ov)     Pin 6
+    VCC (5v)     Pin 2
+    SDA          Pin 3 (GPIO2)
+    SCL          Pin 5 (GPIO3)
+\\
+You need to ensure that the I2C pins are active:
+\\
+    sudo raspi-config
+    Advanced Options
+    I2C
+    Where you see the message -  Would you like the ARM I2C interface to be enabled?
+    Select Yes, then exit this menu system
+    Reboot for the changes to take effect
+\\
+Once the OS is installed and the LCD is connected, the libraries can be installed:
+\\
+Ensure you are in  your home folder (probably /home/pi)\\
+\\
+From the command line:
+\\
+    git clone https://github.com/the-raspberry-pi-guy/lcd
+    cd lcd
+    sudo sh install.sh (RPi will auto reboot)
+\\
+Once the Pi has rebooted:
+\\
+    Navigate to your home folder (probably /home/pi)
+    cd lcd
+    edit lcddriver.py to ensure the ADDRESS = 0x27 is the correct address (some are 0x20)

+I found this guide by doing this YouTube search:

+\\
+To start the demo LCD code:
+\\
