The project is abandoned, but that does not mean it's unsafe. If I find any vulnerabilities, I'll patch them as fast as I can. If you find any vulnerabilities, please let me know. See my profile for contact information.
It's safe to use it for now.
Do:
pip install -r requirements.txt
python3 main.py
You'll need an .env file with following contents:
TOKEN="YOUR_BOT_TOKEN"
