 Golang is not a pure object oriented programming language, and there is no native constructor. In this SDK, every struct has an ***Init*** function for each struct, you must call Init function first, otherwise the member variables may not be initialized expected.
 
+###Logging
+
+This SDK uses the high performance logging library [zap](https://github.com/uber-go/zap), which provide different kind of loggers. To better support format message, this SDK uses the SugaredLogger, and wrapped a few interfaces in package *logging/applogger*. It has below features:
+
+1. Logging target is console (In the future we will support output to file)
+2. Support multiple levels (Fatal, Error, Panic, Warn, Info and Debug) and minimum log level
+3. Support colorful text (by default)
+
+You can customize your own logging by updating *applogger.go* file.
