 ## How To Run
 
-A configuration file may be provided through standard input. Without a configuration file, execute `python main.py`. By default, all of the available distributions will be checked. With a configuration file, execute `python main.py < name_of_config_file.in`, for example, `python main.py < example.in`. In this case, only the distributions listed in the configuration file will be checked.
