+- Flipkart is starting a new vehicle rental service called FlipKar. In this service, we will rent different kinds of vehicles such as cars and bikes.
+
+	- Features:
+		Rental service have multiple branches throughout the city.
+		Each branch has limited number of different kinds of vehicles. 
+		Each vehicle can be booked with predefined price per unit time slot. For simplicity, current pricing model does not support dynamic pricing or update on prices based on seasonality.
+		Each vehicle can be booked in multiples of 1 hour time slot.
+		All bookings should be made before the start time of particular booking.
+	
+	- Requirements:
+		Onboard a new branch with available vehicle.
+		Onboard new vehicle(s) of existing type to a particular branch.
+		Rent vehicle for a time slot and a vehicle type (lowest price as the default choice of selection of vehicle, this should be extendable to any other strategy). While booking a vehicle if 
+                availability is not there, then it should fallback to another available branch, which is derived based on the vehicle selection strategy.
+		A system view should be made available, such as currently booked vehicles, available vehicles of all the branches.
+	
+	- Test cases: 
+		(Test-cases are defined for understanding feature requirements only. Please model it appropriately based on your service implementation)
