 # Step 1: Establish the layers
 
-  # Write a list of the layers here
+  # Layer 1: Drivers - Includes the drivers id and their associated ride information
+  # Layer 2: Rides - Houses each drivers set of ride information.
+  # Layer 3: Ride Information - Includes each ride's information (date, cost, rating, rider_id)
 
 ########################################################
 # Step 2: Assign a data structure to each layer
 
   # Copy your list from above, and write what data structure each layer should have
 
+    # Layer 1: Drivers, Data Structure: Hash
+    # Layer 2: Rides,  Data Structure: Array
+    # Layer 3: Ride Information, Data Structure: Hash
