Discogram
Discogram is a very simple discord and telegram bot that only does one thing: Notify on telegram when someone joins / leaves a vocal discord channel.
To run it you will have to specify a discord token and a telegram token.
You will also need the telegram chat id on which to notify
To run it you simply install the requirements defined in the requirements.txt (discord.py and requests):
pip install -r requirements.txt
And run discord.py:
python discord.py
