   # Write a list of the layers here
 
-########################################################
+## There will be two layers.  The first layer will be based on the number of rows and the second layer will be based on the columns. Future data structures will be created from this inital layering of data.
+
+############################################################
 # Step 2: Assign a data structure to each layer
 
   # Copy your list from above, and write what data structure each layer should have
+#Layer One: An array. Each array will correlate to a row of data.
+#Layer TWo: A hash. The key for each hash will be the column heading. The value for each hash will be the value in the cell.
