 *What is this thing you call ABC?*
     ``GraphI`` does not just provide graph *implementations*, but also an efficient graph *interface*.
-    This interface is defined by the :py:class:`graphi.abc` :term:`abstract base classes <abstract base class>`.
+    This interface is defined by the :py:mod:`graphi.abc` :term:`abstract base classes <abstract base class>`.
 
     Any custom graph implementation can be made a *virtual* subclass of these ABCs.
     This allows you to adopt graph implementations optimized for your use-case without changing your code.
