Extra Note:
For several usage in example when the terminal is closed, or computer is shut down. Not all steps need to be done again, jsut activate the venv with the name myvenv (if not allready acitvated) like in step 4 and steps 8,9 need to be done.
For deactivating the venv if needed navigate to packing_polygons\mysite and write: myvenv\Scripts\deactivate.
