What's a Procfile 👀

I recently deployed a Python application on Heroku, there I encountered a Procfile. This is what I got to know :

• The Procfile is a simple text file that is named Procfile without a file extension. For example, Procfile.txt is not a valid Procfile.
• It specifies the commands that are executed by the app on startup. For e.g A Django server.
• Example: If you want to run a python script on Heroku, your Procfile content should be worker: python script.py
