+@title[#:tag "graph-typed"]{dds/graph-typed: Incomplete Typed Interface to graph}
+
+@defmodule[dds/graph-typed]
+
+@bold{DISCLAIMER:} This is @bold{not} a complete typed interface to Stephen
+Chang's @hyperlink["https://docs.racket-lang.org/graph/index.html"]{graph
+library}.  Read on for more details.
+
+Stephen Chang's
+@hyperlink["https://docs.racket-lang.org/graph/index.html"]{graph library} is
+used in dds to represent different kinds of graphs (state graphs, interaction
+graphs, graphs of interaction processes, etc.).  This module adds types to the
+functions which are used in dds.  These types do not necessarily capture the
+signatures of the functions entirely, and are mainly meant for internal use.
+I may eventually consider contributing something similar to Stephen Chang's
+library, but it would have to be a more polished product than this module is at
+the moment.
