 KylinPlayer
 ===========
 
-A Cross Platform OpenSource Mini Music Player with OSD of BaiduFM on Ubuntu Kylin Linux, Mac OS X and Windows. 
+A Cross Platform OpenSource Mini Music Player with OSD of BaiduFM on Ubuntu Kylin Linux, Mac OS X and Windows.
+
+这些个示例项目是2014年7月底在长沙某高校的一个为期三天的一个UbuntuKylin平台的Qt5开发技术的一个培训项目;
+主要为了在高校师生群体中推广UbuntuKylin以及开源操作系统和开源软件, 课程借以介绍Qt5的一些简单使用来推广Qt开发.
+当时上课没有及时的录制视频,后来单独复述录制了此课程的视频教程,现已把视频公开在51cto学院;
+为了代码和视频配套,供网友下载参考,所以把代码也开源在此(Github).
+
+欢迎大家去学习和改进. 如果有兴趣去进一步完善美化此项目, 可以联系我.
+
+基本要求:
+OS:	Ubuntu/Mac OS X/Windows
+SDK:Qt5.x
+IDE:Qt Creator
