+======================================
+Технические требования «Gilded Rose»
+======================================
+
+Привет и добро пожаловать в команду «Gilded Rose». Как вы знаете, мы небольшая гостиница удобно расположенная
+в известном городе под руководством дружественного управляющего по имени Эллисон. Также мы занимаемся покупкой
+и продажей только самых лучших товаров. К несчастью, качество наших товаров постоянно ухудшается по мере приближения
+к максимальному сроку хранения. Существует информационная система, которая ведет переучет всех товаров. Система
+была разработана рубаха-парнем, по имени Leeroy, который отправился за поисками новых приключений. Ваша задача
+заключается в том, чтобы добавить новый функционал в нашу систему, чтобы мы могли начать продавать новую категорию
+товаров.
+
+В общих чертах система работает следующим образом:
+
+	- Все товары имеют свойство «sellIn» (срок хранения), которое обозначает количество
+	дней в течение которых мы должны продать товар;
+	- Все товары имеют свойство «Quality» (качество), которое обозначает насколько качественным является товар;
+	- В конце дня наша система снижает значение обоих свойств для каждого товара.
+
+Довольно просто, не правда ли? Тут-то и начинается самое интересное:
+
+	- После того, как срок храния прошел, качество товара ухудшается в два раза быстрее;
+	- Качество товара никогда не может быть отрицательным;
+	- Для товара «Aged Brie» качество увеличивается пропорционально возрасту;
+	- Качество товара никогда не может быть больше, чем 50;
+	- «Sulfuras» является легендарным товаром, поэтому у него нет срока хранения и не подвержен ухудшению качества;
+	- Качество «Backstage passes» также, как и «Aged Brie», увеличивается по мере приближения к сроку хранения.
+	Качество увеличивается на 2, когда до истечения срока хранения 10 или менее дней и на 3,
+	если до истечения 5 или менее дней. При этом качество падает до 0 после даты проведения концерта.
+
+Недавно мы нашли поставщика магических товаров. Для того, чтобы продавать его товары необходимо обновить нашу
+систему следующим образом:
+
+	- «Conjured» товары теряют качество в два раза быстрее, чем обычные товары.
+
+Не стесняйтесь вносить любые изменения в метод «UpdateQuality» и добавлять любой новый код до тех пор,
+пока система работает корректно. Тем не менее, не меняйте класс «Item» или его свойства, так как он принадлежит
+сидящему в углу гоблину, который очень яростен и поэтому выстрелит в вас поскольку не верит в принцип
+совместного владения кодом (вы можете сделать метод «UpdateQuality» и свойства класса «Item» статическими
+если хотите, мы вас прикроем).
+
+Просто для уточнения, товар никогда не может иметь качество выше чем 50, однако легендарный товар «Sulfuras»
+имеет качество 80 и оно никогда не меняется.

+Gilded Rose 需求描述
+======================================
+
+
+欢迎来到镶金玫瑰(Gilded Rose)团队。如你所知，我们是主城中的一个小旅店，店主非常友好，名叫Allison。我们也售卖最好的物品。不幸的是，物品品质会随着销售期限的接近而不断下降。
+我们有一个系统来更新库存信息。系统是由一个无名之辈Leeroy所开发的，他已经不在这了。
+你的任务是添加新功能，这样我们就可以售卖新的物品。
+
+先介绍一下我们的系统：
+
+	- 每种物品都具备一个`SellIn`值，表示我们要在多少天之前把物品卖出去，即销售期
+	- 每种的物品都具备一个`Quality`值，表示物品的品质
+	- 每天结束时，系统会降低每种物品的这两个数值
+
+很简单吧？这还有些更有意思的：
+
+	- 一旦销售期限过期，品质`Quality`会以双倍速度加速下降
+	- 物品的品质`Quality`永远不会为负值
+	- "Aged Brie"的品质`Quality`会随着时间推移而提高
+	- 物品的品质`Quality`永远不会超过50
+	- 传奇物品"Sulfuras"永不到期，也不会降低品质`Quality`
+	- "Backstage passes"与aged brie类似，其品质`Quality`会随着时间推移而提高；当还剩10天或更少的时候，品质`Quality`每天提高2；当还剩5天或更少的时候，品质`Quality`每天提高3；但一旦过期，品质就会降为0
+
+
+我们最近签约了一个召唤物品供应商。这需要对我们的系统进行升级：
+
+	- "Conjured"物品的品质`Quality`下降速度比正常物品快一倍
+
+请随意对UpdateQuality函数进行修改和添加新代码，只要系统还能正常工作。然而，不要修改Item类或其属性，因为那属于角落里的地精，他会非常愤怒地爆你头，因为他不相信代码共享所有制（如果你愿意，你可以将UpdateQuality方面和Items属性改为静态的，我们会掩护你的）。
+
+再次澄清，每种物品的品质不会超过50，然而"Sulfuras"是一个传奇物品，因此它的品质是80且永远不变。

+; 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 it's
+;   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.

+TL;DR;
+-------
 run-once.sh runs your tests once
 
-Assumptions:
+Before this will work you will need:
   - make and a C++ compiler (like gcc) is installed on your system and is in the PATH
-  - The GTest framework is in the directory gtest.
+  - The GTest framework in the directory gtest.
   - If your IDE does the compilation and linking, you should remove the first 3 lines
     in the run-once.sh file.
+
+More Verbose Instructions
+-------------------------
+
+Create a clone of both GildedRose-Refactoring-Kata and googletest in a directory we'll call ${ROOT_INSTALL_DIR}:
+
+    cd ${ROOT_INSTALL_DIR}
+    git clone https://github.com/emilybache/GildedRose-Refactoring-Kata
+    git clone https://github.com/google/googletest
+
+Make googletest by running make in subfolder googletest/googletest/make:
+
+    cd googletest/googletest/make
+    make
+
+Create a softlink in the GildedRose-Refactoring-Kata clone pointing at the googletest code:
+
+    cd ${ROOT_INSTALL_DIR}/GildedRose-Refactoring-Kata/cpp
+    ln -s ${ROOT_INSTALL_DIR}/googletest/googletest gtest
+
+Make the GildedRose-Refactoring-Kata:
+
+    make
+
+Then you should be able to run the tests:
+
+    ./run_once.sh
+
+If you have been successful, then you should see a failing test, "GildedRoseTest.Foo".
