-Instructions
+## Task
 -------
+To write a Takeaway programme which will include a menu that lists dishes & prices of each dish. Customers will be able to use the programme to place an order & select several dishes they want with quantities, the programme will be able to calculate the total cost of the order as well.
+I will be using Twilio in order to send text messages to customers to inform them when their order will be delivered. Within the testing process, I will try to use stubs and doubles in order to isolate my tests.

 * Hints on functionality to implement:
   * Ensure you have a list of dishes with prices
   * The text should state that the order was placed successfully and that it will be delivered 1 hour from now, e.g. "Thank you! Your order was placed and will be delivered before 18:52".
