 We now want a layer that loads up some ZCML from a file. The default
 is ``ftesting.zcml``, but here we'll load a test ``testlayer.zcml``.
+We can also choose to provide extra ZCML features (here, "devmode").
 
 .. doctest::
 
    >>> from zope.component.testlayer import ZCMLFileLayer
    >>> import zope.component.testfiles
    >>> zcml_file_layer = ZCMLFileLayer(
    ...     zope.component.testfiles,
-   ...     'testlayer.zcml')

 Since the ZCML sets up an adapter, we expect the tests to pass:
