 ===== Introduction =====
-This document mainly introduces the WiringPi. You will learn how to use the WiringPi to control the GPIO on the 40-Pin Header.
+WiringPi is a C++ library for Raspberry Pi, we port it to Khadas SBC, With this library you can use many of the functionalities provided by the GPIO header: digital pins, SPI, I2C, UART, etc.
