+The functionality of TensorFlow (TF) is implemented in many languages and one of them is C++, 
 but Python is used as an interface (front-end) between the backend system and the users. 
-The TF C++ API his built on TensorFlow Session (in the old version) and on TensorFlow ClientSession (in the new version). 
-One can make use either of these to execute TensorFlow graphs that have been built using the Python API and serialized to a `GraphDef`.

 ## C++ API for TensorFlow
 
 The runtime of TensorFlow is written in C++, and mostly, C++ is connected to TensorFlow through header files in `tensorflow/cc`. 
-The C++ API is still in experimental stages of development, and also the documentation is being updated, 
-meaning that it lacks of information and tutorial about how to use TensorFlow API.
