 Every student in the class has a git repository (a place where you can store completed assignments). This git repository can be accessed from:
-[https://mit.cs.uchicago.edu/cmsc13600-spr-19/<your cnetid>.git]
+[https://mit.cs.uchicago.edu/cmsc13600-spr-20/<your cnetid>.git]
 
 The first thing to do is to open your terminal application, and ``clone`` this repository (NOTE skr is ME, replace it with your CNET id!!!):
 ```
-$ git clone https://mit.cs.uchicago.edu/cmsc13600-spr-19/skr.git cmsc13600-submit
+$ git clone https://mit.cs.uchicago.edu/cmsc13600-spr-20/skr.git cmsc13600-submit
 ```
 Your username and id is your CNET id and CNET password. This will create a new folder that is empty titled cmsc13600-submit. There is similarly a course repository where all of the homework materials will stored. Youshould clone this repository as well:

 Extract, transform, load (ETL) is the general procedure of copying data from one or more sources into a destination system which represents the data differently from the source(s). In this project, you will write some of the core primitives in an ETL system.

 In this assignment, you will implement an out-of-core
 version of the group by aggregate (aggregation by key)
 seen in lecture. You will have a set memory limit and 
 you will have to count the number of times a string shows 
 up in an iterator. Your program should work for any limit 
-> 20.
+less than 20.
