What to eat is an APP specially designed for students in CQU and for those who have Choice Phobia Disorder. Inside this APP, we build a huge database to store all information about dished in canteen of CQU. By a random algorithm we are able to make a choice on what to eat for meals for users. Unfortunately, in a limited time we failed to support English. So in this document, we are going to show foreigners the basic methods on how to run this APP. When you click on our icon, you will come to the main frame which states four small green buttons and one large pink button. These four buttons separately stand for:喜欢的（My favors）,黑名单（black list）,店家一览（skim of all stores）,菜单一览（skim of all dishes）.Clicking on them you will see a list of different things. The pink button is for you to click so that we will go to the page of selecting conditions and running a result. Now suppose you are in the second page, you will face a lot of available conditions for you to choose, but you don’t have to constrain them. IF you do ,we will help select one from those who fit for your given conditions. From the top to the button, the conditions are: canteen, hall, store, price, and taste. Under them are for you to choose whether to select from your favor list and ignore those in your blacklist. After you settle all, you can click on the pink button, and you will get a result and turn into the result page. On the result page, you will see what to eat and detailed information about the dish. You can choose to join this dish into your favor list or blacklist . If you are done, you can go back to main frame. If you are not OK with it ,you can go back to the second page to work again by clicking on the last button on this page.
