 - ``DataFlow::Pathgraph`` is the path graph module you need to import from the standard CodeQL libraries.
 - ``source`` and ``sink`` are nodes on the `path graph <https://en.wikipedia.org/wiki/Path_graph>`__, and ``DataFlow::PathNode`` is their type.
-- ``Configuration`` is a class containing the predicates which define how data may flow between the ``source`` and the ``sink``.
+- ``MyConfiguration`` is a class containing the predicates which define how data may flow between the ``source`` and the ``sink``.
 
 
 The following sections describe the main requirements for a valid path query.
