 ## How to Run?
 Using demo config file and requirements.txt file located at `./files` as example, run
 ```bash
-python pack.py --conf_path ./files/centos_config.json
+python pypack.py --conf_path ./files/centos_config.json
 # or
-python pack.py --conf_path ./files/ubuntu_config.json
+python pypack.py --conf_path ./files/ubuntu_config.json
 ```
 After execution, the last line of logs will tell you where to get your python-env tar.gz file.
 
 If you do not want `git clone` the responsitory, you can just run 
 ```bash
