Hi, JiangJiang, are you there? I think the README is too simple also. Could you also write a more detailed description for non-experts to use?

The User manual can be found in http://people.sutd.edu.sg/~yue_zhang/doc/index.html, but this is the old one, the only difference is compiling method, how to train and test is the same. I will update the document later.
