 ========================================
 
 When creating line magics, you may need to access surrounding scope  to get user
-variables (e.g when called inside functions). IPython provide the
+variables (e.g when called inside functions). IPython provides the
 ``@needs_local_scope`` decorator that can be imported from
 ``IPython.core.magics``. When decorated with ``@needs_local_scope`` a magic will
 be passed ``local_ns`` as an argument. As a convenience ``@needs_local_scope``
 can also be applied to cell magics even if cell magics cannot appear at local
 scope context.
 
+Silencing the magic output
+==========================
+
+Sometimes it may be useful to define a magic that can be silenced the same way
+that non-magic expressions can, i.e., by appending a semicolon at the end of the Python
+code to be executed. That can be achieved by decorating the magic function with
+the decorator ``@output_can_be_silenced`` that can be imported from
+``IPython.core.magics``. When this decorator is used, IPython will parse the Python
+code used by the magic and, if the last token is a ``;``, the output created by the
+magic will not show up on the screen. If you want to see an example of this decorator
+in action, take a look on the ``time`` magic defined in
+``IPython.core.magics.execution.py``.
