+	\begin{quote}
+		Participatory Budgeting (PB) is a democratic process in which
+		community members decide how to spend part of a public budget.

+		Each project has a cap $q_p = 1$ and $x_p = [0,1]$ denotes the
+		fraction of project $p\in P$ that is completed. The set of
+		feasible budget allocations under a budget $B = 1$ is therefore defined as
+		\[ \{ \vec{x} : \sum_{p\in P}{x_p}\leq 1 \}. \]

+		A project that seeks to donate a bounded amount of money to a
+		charity.
