+nzmqt - A lightweight C++ [Qt][] binding for [ZeroMQ][]
+======================================================
+
+nzmqt is a re-implementation of the approach taken by the [zeromqt][] library. The idea 
+is to integrate ZeroMQ into the Qt event loop, mapping ZeroMQ message events onto 
+Qt signals. The original implementation also provides a Qt-like API
+which allows to represent messages as QByteArray instances. While I took this idea
+and the original implementation as a source of information, I've done a completely
+new implementation. Not only in order to get rid of some short comings, but also 
+because I wanted to be sure I can use the code in my projects without problems,
+because until now zeromqt's author hasn't officially released his work under a certain
+(open source) license. Consequently, nzmqt is released to the public under the 
+simplified BSD license. So you can use the code in your projects without any fear.
+
+While zeromqt works fine for non-multi-part messages, it doesn't support multi-part
+messages yet. Also, a lot of code duplicates code of ZeroMQ's standard C++ binding.
+But this requires to take care of both implementations. So in contrast to the original
+implementation, nzmqt reuses as much code of ZeroMQ's original C++ binding as possible
+by using inheritance. Additionally, several things have been changed from a user's
+perspective. In summary, nzmqt contains the following changes compared to zeromqt:
+
+* The implementation is a complete re-write in the sense that it doesn't duplicate code
+of ZeroMQ's official C++ binding anymore. Instead, it builds upon existing code
+through inheritance and, hence, it will likely benefit from future bugfixes and
+enhancements targeted at ZeroMQ's C++ binding.
+* All classes are placed into a separate namespace 'nzmqt'.
+* This version now also supports ZeroMQ's multi-part messages.
+* The initial support for using Qt's way of handling errors using error codes 
+has been dropped. Instead, this code only throws exception originally thrown
+by ZeroMQ's official C++ API. Note that although it looks like 'ZMQException'
+is a new custom exception class there is no custom exception class, but only
+a simple typedef which places the original exception class into the new
+namespace giving it a new name.
+* As with ZeroMQ's C++ binding all classes are contained within a singe header
+file which makes integrating this Qt binding very easy.
+* There is no 'ZmqContext' singleton anymore. Instead you can create your
+own instance of a concrete subclass of 'ZMQContext' yourself.
+* The socket class 'ZMQSocket' now also inherits from QObject, so you can
+add it as a child to any QObject parent as you know it from Qt.
+* The code is officially licensed under the simplified BSD license.
+* Not only PUB-SUB, but also REQ-REP and PUSH-PULL are supported.
+
+Status
+------
+
+See the [official bug tracker](https://github.com/jonnydee/nzmqt/issues "https://github.com/jonnydee/nzmqt/issues").
+
+Usage
+-----
+
+As ZeroMQ's C++ binding this Qt binding only consists of a single C++ header file
+which you need to include in your project.
+
+Consequently, using 'nzmqt' in a Qt project is as simple as adding that single header
+file to your project's .pro file as follows (assumed you use QT Creator).
+
+    HEADERS += nzmqt/nzmqt.hpp
+
+If not already done, you also need to link against ZeroMQ library:
+
+    LIBS += -lzmq
+
+Of course, you need to make sure the header file as well as the ZeroMQ library
+can be found by your compiler/linker.
+
+As nzmqt uses C++ exceptions for error handling so you will need to catch them
+by overriding QCoreApplication::notify() method. The included sample will
+show you how this can be done. 
+
+Included Samples
+----------------
+
+Currently, there are samples showing PUB-SUB, REQ-REP and PUSH-PULL protocol with multi-part
+messages in action. They also show how to deal with exceptions in Qt.
