-# Class Manager
-
-## Product Inventory Project 
-
-## Objectives
-
-1. To demonstrate your understanding of objects and functions
-2. To demonstrate your understanding of controlling execution
-3. To demonstrate your understanding of access control
-4. To demonstrate your understanding of reusing classes
-
-
-## Overview
-
-Create an application which manages an inventory of products. Create a product class which has a price, id, and quantity on hand. Then create an inventory class which keeps track of various products and can sum up the inventory value.
-
-## Unit Test
-
-UML is required
-Unit test in  place before proceeding with code
-
-## Instructions
-
-1. In your main class initialize your manager and populate your inventory
-2. Demonstrate calling methods on your manager
-3. Print all output to screen
+# Product Inventory Project
+* **Objective** - to implement an `InventoryManager` which interacts with a _composite_ `Inventory` object by parsing incoming commands from a _composite_ `Console` object.
+* **Purpose** - to demonstrate understanding of
+	* objects and functions
+	* controlling execution
+	* access control
+	* reusing classes
+
+
+# Part 1.0 - Create class `Product`
+* Create a `Product` class.
+	* declare a field named `id` of type `Long`.
+	* declare a field named `price` of type `Double`.
+	* declare a field named `quantity` of type `Integer`.
+	* define a constructor, which has paramters of type `(Long, Double, Integer)` used to set each of the respective fields.
+	* define a nullary constructor, which sets each field to a `null` value.
+	* define getters and setters for each of the fields
+
+# Part 2.0 - Create class `Inventory`
+* Create an `Inventory` class.
+	* declare a field named `productList` of type `List` of `Product` objects.
+	* define a constructor, which has a paramter of type `List` of `Product` used to set the respective field.
+	* define a nullary constructor, which sets the `productList` field to a `new` instance of `ArrayList`.
+	* define method named `add`, which adds a `Product` to the _composite_`productList`.
+	* define method named `remove`, which makes use of a `Product product` parameter to remove a `Product` from the _composite_`productList`.
+	* define method named `contains`, which makes use of a `Product product` parameter to return `true` if the provided `Product` has been added to the `productList` field.
+	* define method named `findById` which makes use of a `Long id` parameter to return a `Product` with the respective `id` from the `productList` field.
+	* define method named `removeById`, which makes use of a `Long id` parameter to remove a `Product` with the respective `id` from the `productList` field.
+	* define method named `getTotalQuantity` which returns the sum of the `quantity` fields of the `Product` objects in the `productList` field.
+	* define method named `getTotalValue` which returns the product of the `quantity` and `price` field of each of the `Product` objects in the `productList` field.
+	* define getters and setters for each of the fields
+
+
+# Part 3.0 - Create class `Console`
+* Create a `Console` class.
+	* declare a field named `scanner` of type `Scanner`.
+	* declare a field named `out` of type `PrintStream`.
+	* define a constructor which makes use of a `(InputStream inputStream, PrintStream printStream)` parameter to set the composite `scanner` and `out` fields.
+	* define a nullary constructor, which
+		* sets the `scanner` field to a new `Scanner` which takes an argument of `System.in`
+		* sets the `out` field to `System.out`
+	* define a method named `println`, which makes use of a `String prompt` parameter to print to the `out` field.
+	* define a method named `getStringInput` which makes use of a `String prompt` parameter to prompt the user for some input, then returns the input of the user as a string.
+	* define a method named `getStringInput` which makes use of a `String prompt` parameter to prompt the user for some input, then returns the input of the user as a string.
+	* define a method named `getDoubleInput` which makes use of a `String prompt` parameter to prompt the user for some input, then returns the input of the user as a double.
+	* define a method named `getIntegerInput` which makes use of a `String prompt` parameter to prompt the user for some input, then returns the input of the user as a integer.
+	* define a method named `getLongInput` which makes use of a `String prompt` parameter to prompt the user for some input, then returns the input of the user as a long.
+	
+	
+# Part 4.0 - Create class `InventoryManager`
+* Create an `InventoryManager` class.
+	* declare a field named `inventory` of type `Inventory`
+	* declare a field named `console` of type `Console`
+	* define a constructor which makes use of a `(Inventory inventory, Console console` parameters to set the `inventory` and `console` fields to the respective values
+	* define a nullary constructor, which initializes the `inventory` and `console` fields to nullary-constructed `Inventory` and nullary-constructed `Console`.
+	* define a method named `getUserInput` which prompts the user to input some variation of `add`, `remove`, `view inventory`, `view product`, or `exit`, then returns the input as a `String.
+	* define a method named `add` which makes use of user to input to construct a new `Product` and add it to the `inventory` field.
+	* define a method named `remove` which prompts a user to input an `id` and removes a `Product` with the respective `id` from the `inventory` field.
+	* define a method named `viewProduct` which prompts a user to input an `id` and displays details about a `Product` with the repspective `id` from the `inventory field.
+	* define a method named `viewInventory` which which displays the contents of the inventory.
+	* define getters and setters for each of the fields.
