+Architectures
+=============
+
+Architectures contain all the classes that implement the neural network related stuff for the agent.
+Since Coach is intended to work with multiple neural network frameworks, each framework will implement its
+own components under a dedicated directory. For example, tensorflow components will contain all the neural network
+parts that are implemented using TensorFlow.
