 Please note that the best tools for debugging are the `ones that ship with
 Gecko`_. This page doesn't describe how to use those with Marionette. Also see
 a related topic about `using the debugger with Marionette`_ on MDN.

-Storing Logs on the Server
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-By calling :func:`~Marionette.log` it is possible to store a message on the
-server.
-Logs can later be retrieved using :func:`~Marionette.get_logs`. For example::
-
-    try:
-        marionette.log("Sending a click event") # logged at INFO level
-        elem.click()
-    except:
-        marionette.log("Something went wrong!", "ERROR")
-
-    print(marionette.get_logs())
-
-Disclaimer: Example for illustrative purposes only, don't actually hide
-tracebacks like that!

 manipulated. Either because it happens too fast, the window isn't big enough or
 you are manipulating a remote server! There are two methods that can help you
 out. The first is :func:`~Marionette.screenshot`::
