 ### TensorFlow C API Library Installation
 
-Perfect-TensorFlow is based on TensorFlow C API, i.e., `libtensorflow.so` on runtime.
-This project contains an express CPU version installation script for this module on both macOS / Ubuntu Linux, and will install the dynamic library into path `/usr/local/lib/libtensorflow.so`. You can download & run [`install.sh`](https://github.com/PerfectlySoft/Perfect-TensorFlow/blob/master/install.sh). Before running this script, please make sure that `curl` has been installed onto your computer.
