+# Step 1: Establish the layers
+
+# Write a list of the layers here
+# I set up an array named "drivers"
+# The indices of drivers array are driver1 - driver4, all hashes containing
+# the :keys ride_id, pay, rating,and dates_active.
+# corresponding elements were fed into an array, making the
+# data structure an array of hashes with arrays as values.
+#
+########################################################
+# Step 2: Assign a data structure to each layer
+# top layer - array (4 elements)
+# 2nd layer - hash (4 elements containing inside array of up to 3 elements)
+
+# Copy your list from above, and write what data structure each layer should have
+# top layer - array (4 elements) - should contain hash
+# 2nd layer - hash -  4 elements containing a symbol as key and  array of up to 3 elements as value)
+# values are arrays containing strings and integers.

+# Step 3: Make the data structure!
+
+# Setup the data strcture and manually write in data presented in rides.csv
