+AnyWay - plan city trips your way
+
+AnyWay is a mobile application that helps users plan city trips. The app allows users to specify their preferences and constraints, and then generates a personalized itinerary for them. The planning follows some guiding principles:
+- **Personalization**:The user's preferences should be reflected in the choice of destinations.
+- **Efficiency**:The itinerary should be optimized for the user's constraints.
+- **Flexibility**: We aknowledge that tourism is a dynamic activity, and that users may want to change their plans on the go.
+- **Discoverability**: Tourism is an inherently exploratory activity. Once a rough itinerary is generated, detours and spontaneous decisions should be encouraged.
