If you dont have install pip3 (this works in linux) $ sudo apt-get -y install python3-pip
After that navigate to folder where repository is located $ cd /your/directory/with/this/repository
Add execution permission to file $ chmod u+x name_of_script.py
After that install dependencies $ pip3 install -r requirements.txt
$./busy_hours.py <start_date> <end_date> <your_token_here>
You need to get api-token from giosg.
There is also possibility to use default values. api-token is not included so you have to add it.
$ ./busy_hours.py
