-def loadDLL(f):
+Before using the library, you must load the ``libpycpdf`` and ``libcpdf`` DLLs.
-    """Load the libpycpdf DLL from a given file, and set up pycpdflib."""
+This is achieved with the ``pycpdf.loadDLL`` function, given the filename or
+full path of the ``libpycpdf`` DLL.
+
+On Windows, you may have to call ``os.add_dll_directory`` first. On MacOS, you
+may need to give the full path, and you may need to install ``libcpdf.so`` in a
+standard location ``/usr/local/lib/``, or use the ``install_name_tool`` command
