If you need help setting up Python, refer to my Python set up script in the Ubuntu set up repo.

Download "onion-extract" into your desired folder (e.g. "onion-extract"). Set up Python virtual environment (e.g. env).

python3 -m venv env

Activate virtual enviornment.

source env/bin/activate

Install required modules.

pip3 install -r requirements.txt

Sample "onion-extract" command.

python3 onion-extract.py -o [download folder name] [onion url]
