 These HashMap implementations were my final project for **CS 261 - Data Structures**
 at Oregon Sate. hash\_map\_oa.py features open addressing with quadratic probing
-while hash\_map\_sc.py uses separate chaining.
+while hash\_map\_sc.py uses separate chaining to handle collisions. Both implementations
+use a dynamic array for the underlying hash table, however hash\_map\_sc.py uses a
+singly linked list for each bucket, and hash\_map\_oa.py uses a single HashEntry
+object at each index of the array.
