-	\section{Rules}
-
-	This handout contains a set of problems. \par
-	Each is marked with a few gold stars, which you collect by presenting a solution.
-
-	\vspace{2mm}
-
-	Below each problem is a list of hints, written next to their cost. \par
-	To get a hint, you must pay the marked number of stars. \par
-	Hints are usually provided in order, and are the same for all groups. \par
-
-	\vspace{2mm}
-
-	There is one exception: instructors may offer certain hints for a reduced fee,
-	judging by your explanation of what you have so far.
-
-	\begin{instructornote}
-		This exception is for groups that are stuck on the last bit of a problem. \par
-		If they've solved most of it, give them the information they already know
-		for a steep discount (or even for free).
-	\end{instructornote}
-
-
-
-	An example problem is below.
-
-	\vspace{4mm}
-
-	\generic{Problem $0$:}
-	\starvalue{4}
-
-	This is a problem that's worth four points. \par
-	Two hints are available. The first costs two stars (of the four available). \par
-	The second costs one of the two stars available \textit{after} revealing the first hint.
-
-	\begin{hintlist}
-		Hint 1:
-		\hintcontent{2}{4}{This is a hint. Only instructors see this.}
-
-		Hint 2:
-		\hintcontent{1}{2}{This is another hint.}
-	\end{hintlist}
-
-	\vfill
-
-	You may notice that hints often cost a significant fraction of their problem's score. \par
-	This is intentional---don't ask for hints unless you're very, very stuck.
