 ### Requirements
 
+#### Pages
+
+1. Main Page
+    - Clock-like interface which has a pointer hand going towards the current date.

+1. Location Entry
+    - Opens when a pie wedge is clicked.
+    - Allows the user to enter a zip_code OR lat_num + long_num. Not both.

+
+### Test Cases
+
+1. App opens and displays any previously entered locations.
+    - Screenshot of app
+
+1. App loads weather data, choosing the DB cache first.
+
+
+1. If the DB is down, app accesses weather API directly.
+    - Take down the DB, or put in an incorrect URL/port.
+    - Open app and note a few temps and the last_update_date.
+    - After the update takes place, note the new temps and last_update_date.
