+# LcdControl Example program
+
+### Compile example program
+This example needs some static libraries and header files located under '/Doly/libs' & '/Doly/include'
+Make sure you have already copy '/Doly' folder under your root directory.
+
+```bash
+g++ -L../Doly/libs -I../Doly/include -Wall -o test main.cpp -lLcdControl
+```
