-===== Installing and Configuring the LIRC and the driver module  =====
+== Example for ODROID-XU4 using 2x15 pins Expansion Connectors ==
+For example, Pin #26 (GPIO #24) is used and following instructions will be described with the GPIO value. \\
+^ LED side   ^  Connector   ^
+|  VCC  | Pin #29 - 1.8V Power  |
+|  GND  | Pin #28 - Ground  |
+|  GPIO  | Pin #26 - GPIO #24   |
+**In case of XU4, voltage level of VDD_IO and GPIO output is 1.8V.\\
+Supposing R2 is 10 Ohm, the actual forward current is around 40mA and voltage difference between P1 and P2 is around 400mV. \\ **

+===== Install LIRC Package  =====
+<code>
+$ sudo apt-get install lirc
+</code>
+Install LIRC package. While installing lirc, you will be asked the device type of IR receiver and transmitter.\\
+Since we will set up later by manual, you can select **None**.\\
+And for further information, please refer to the following wiki page.\\
