-# Step 1: Establish the layers
+# Step 1: Establish the layers: Create a list of the layers you identify.
+# TOP LEVEL: Drivers
+# MIDDLE LAYER: All trips taken
+# BOTTOM LAYER:  Individual Rides Info
 
-# In this section of the file, as a series of comments,
-# create a list of the layers you identify.
 # Which layers are nested in each other?
-# Which layers of data "have" within it a different layer?
+# Bottom layer has the nested info
+#
+# # Which layers of data "have" within it a different layer?
+# driver_array >> drivers_id >>  date- cost -rider_id rating
+
 # Which layers are "next" to each other?
+# date/cost/rider_id/rating
 
 ########################################################
 # Step 2: Assign a data structure to each layer
 
-# Copy your list from above, and in this section
-# determine what data structure each layer should have
+# TOP LEVEL: A Hash of All Drivers info 
+# MIDDLE LAYER:  Is an Array with unique Driver IDs
+# BOTTOM LAYER:  Nested within array is a Hash with individual Ride Info Keys (Date/Cost/Rider_ID/Rating)

 # Step 3: Make the data structure!
-
 # Setup the entire data structure:
-# based off of the notes you have above, create the
-# and manually write in data presented in rides.csv
-# You should be copying and pasting the literal data
-# into this data structure, such as "DR0004"
-# and "3rd Feb 2016" and "RD0022"

-# Step 4: Total Driver's Earnings and Number of Rides
-
-# Use an iteration blocks to print the following answers:
-# - the number of rides each driver has given
-# - the total amount of money each driver has made
-# - the average rating for each driver
-# - Which driver made the most money?
-# - Which driver has the highest average rating?
