-Instructions
+
+Instalation
 -------
+```
+$ git clone https://github.com/LGretzk/takeaway-challenge.git
 
-* Feel free to use google, your notes, books, etc. but work on your own
-* If you refer to the solution of another coach or student, please put a link to that in your README
-* If you have a partial solution, **still check in a partial solution**
-* You must submit a pull request to this repo with your code by 9am Monday morning
+$ cd takeaway-challenge
 
-Task
+$ bundle
+```
+
+Instructions
 -----
 
-* Fork this repo
-* Run the command 'bundle' in the project directory to ensure you have all the gems
-* Write a Takeaway program with the following user stories:
+* Use IRB to require the order.rb file
+
+* Create a new instance of Order to order food.
+
+* Use show_dishes method to see the menu.
+
+* Use add_dish(id, quantity) to order dish.
+
+* Use remove_dish(id) to remove dish from your order.
+
+* Use update_dish_quantity(id, quantity) to update the quantity of your chosen dish.
+
+* Use show_current_order to preview your order.
+
+* Use total to get the total amount you would need to pay for your order.
+
+* Use place_order(Confirmation.new) to place your order.
+
+

 As a customer
@@ -46,38 +54,3 @@ As a customer
 So that I am reassured that my order will be delivered on time
 I would like to receive a text such as "Thank you! Your order was placed and will be delivered before 18:52" after I have ordered
 ```
-
-* 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".
-  * The text sending functionality should be implemented using Twilio API. You'll need to register for it. It’s free.
-  * Use the twilio-ruby gem to access the API
-  * Use the Gemfile to manage your gems
-  * Make sure that your Takeaway is thoroughly tested and that you use mocks and/or stubs, as necessary to not to send texts when your tests are run
-  * However, if your Takeaway is loaded into IRB and the order is placed, the text should actually be sent
-  * Note that you can only send texts in the same country as you have your account. I.e. if you have a UK account you can only send to UK numbers.
-
-* Advanced! (have a go if you're feeling adventurous):
-  * Implement the ability to place orders via text message.
-
-* A free account on Twilio will only allow you to send texts to "verified" numbers. Use your mobile phone number, don't worry about the customer's mobile phone.
-
-> :warning: **WARNING:** think twice before you push your **mobile number** or **Twilio API Key** to a public space like GitHub :eyes:
->
-> :key: Now is a great time to think about security and how you can keep your private information secret. You might want to explore environment variables.
-
-* Finally submit a pull request before Monday at 9am with your solution or partial solution.  However much or little amount of code you wrote please please please submit a pull request before Monday at 9am
-
-
-In code review we'll be hoping to see:
-
-* All tests passing
-* High [Test coverage](https://github.com/makersacademy/course/blob/main/pills/test_coverage.md) (>95% is good)
-* The code is elegant: every class has a clear responsibility, methods are short etc.
-
-Reviewers will potentially be using this [code review rubric](docs/review.md).  Referring to this rubric in advance will make the challenge somewhat easier.  You should be the judge of how much challenge you want this at this moment.
