+# Step 1: Establish the layers
+# 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?
+# Which layers are "next" to each other?
+
+    # The drivers in the data set are a layer, which have 'nested' in them
+    # a set of information. They all have the same type of data, such as cost.
+    # Their cost, rating, date, etc are all 'next' to each other. The drivers
+    # themselves are also next to each other within a different layer as well, 
+    # which contains each trips information.
+########################################################
+# 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
+    # In my code, I have created individual hashes for each trip the driver
+    # has taken. These hashes are nested within an array which belongs to each driver.
+    # Each driver also represents a key in a hash, where the array represents their value.
+
+########################################################
+# 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
