 # The `brandeis-problemset` document class
 
 Brandeis University's computer science (“cosi”) courses often assign “problem
-sets” which require fairly rigorous formatting. The `brandeis-problemset` document
-class, which extends `article`, provides a simple way to typeset these problem
-sets in LaTeX.
