To use the app you need to make sure the requirements are installed. It is best to do this in a virtual environment OR use a Docker container.

sudo apt update && sudo apt install python3-pip python3-venv -y
python3 -m venv venv
. ./venv/bin/activate

Then you can run the tests. This can only be done if the dependencies in requirements.txt are installed.

# In the root of the project
pytest

Or you can run the app.

python3 app.py
