+======================================
+Gilded Rose Requirements Specification
+======================================
+
+Hi and welcome to team Gilded Rose. As you know, we are a small inn with a prime location in a
+prominent city ran by a friendly innkeeper named Allison. We also buy and sell only the finest goods.
+Unfortunately, our goods are constantly degrading in quality as they approach their sell by date. We
+have a system in place that updates our inventory for us. It was developed by a no-nonsense type named
+Leeroy, who has moved on to new adventures. Your task is to add the new feature to our system so that
+we can begin selling a new category of items. First an introduction to our system:
+
+	- All items have a SellIn value which denotes the number of days we have to sell the item
+	- All items have a Quality value which denotes how valuable the item is
+	- At the end of each day our system lowers both values for every item
+
+Pretty simple, right? Well this is where it gets interesting:
+
+	- Once the sell by date has passed, Quality degrades twice as fast
+	- The Quality of an item is never negative
+	- "Aged Brie" actually increases in Quality the older it gets
+	- The Quality of an item is never more than 50
+	- "Sulfuras", being a legendary item, never has to be sold or decreases in Quality
+	- "Backstage passes", like aged brie, increases in Quality as its SellIn value approaches;
+	Quality increases by 2 when there are 10 days or less and by 3 when there are 5 days or less but
+	Quality drops to 0 after the concert
+
+We have recently signed a supplier of conjured items. This requires an update to our system:
+
+	- "Conjured" items degrade in Quality twice as fast as normal items
+
+Feel free to make any changes to the UpdateQuality method and add any new code as long as everything
+still works correctly. However, do not alter the Item class or Items property as those belong to the
+goblin in the corner who will insta-rage and one-shot you as he doesn't believe in shared code
+ownership (you can make the UpdateQuality method and Items property static if you like, we'll cover
+for you).
+
+Just for clarification, an item can never have its Quality increase above 50, however "Sulfuras" is a
+legendary item and as such its Quality is 80 and it never alters.
