 ## Run network in TensorFlow
-Deep learning networks in TensorFlow are represented as graphs where an every node is a transformation of it's inputs. They could be common layers like `Convolution` or `MaxPooling` and implemented in C++ or a custom ones

+Deep learning networks in TensorFlow are represented as graphs where an every node is a transformation of it's inputs. They could be common layers like `Convolution` or `MaxPooling` and implemented in C++. Custom layers could be built by existing TensorFlow operations in python.
