I've only had the time now to play with TastyIgniter. I'm working on an Android app where it will be connected to a usb thermal printer, and when a new order is placed, it will automatically print. The mobile app will also act as a ui for managing the orders. I'd like to create a new extension to implement this feature but looking at the documentation, I'm lost.
For example, it states that to edit the config/events.php for registering events etc., but it doesn't exist. Could you give me a basic example please that prints hello world?
