+# Step 1: Establish the layers
+
+# In this section of the file, as a series of comments,
+# create a list of the layers you identify.
+
+# DriverID array > Rides array > HASH :Date :Cost :Rider_ID :Rating
+
+# Drivers [driver_data] - array
+# drives - array
+# hash of ride info (:Date :Cost :Rider_ID :Rating)
+
+# Which layers are nested in each other?
+
+# ride data (date/cost/rider/rating) inside of drives inside of drivers
+
+# Which layers of data "have" within it a different layer?
+
+# QUESTION how is this question different than above?
+
+# Which layers are "next" to each other?
+
+# The ride info is next to each other on the same level
+
+########################################################
+# 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
+
+# Drivers [driver_data] - array
+# drives - array
+# hash of ride info (: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"
