-This is a refactor for the previous CINN project.
+# CINN : Compiler Infrastructure for Neural Networks

+CINN is a DNN compiler and executor for multiple hardwares. 
+It is designed to provide multiple layers of APIs to make DNN computation easier to define,  faster to execute and more convenient to extend with more hardware backends.
