 Gazebo Transport is an open source communication library that allows sharing
 data between clients. In our context, a client is called a node. Nodes might
-be running within the same process on the same machine or on separate machines located
-around the world. Gazebo Transport is multi-platform (Linux, Mac OS X, and
-Windows), so all the low level details, such as data alignment or endianness, are
-hidden for you.

-Gazebo Transport uses [Google Protocol buffers]
-(https://developers.google.com/protocol-buffers/?hl=en) as the data type for
-communicating between nodes. Users can define their own messages using the
-Protobuf utils, and then exchange them between the nodes. Gazebo Transport
-discovers, serializes and delivers messages to the destinations using a
-combination of custom code and [ZeroMQ] (http://zeromq.org/).

 ## What programming language can I use with Gazebo Transport?
 
-C++ is the native implementation and the only language that has all available library features.
-Python implementation is a wrapper around C++ methods using `pybind11`. It does not support all features like C++, but contains the main features such as publication, subscription and service request.
