+    >>> instrument('NIDAQ')  # Opens the NIDAQ
 
 This will work as long as the string you use isn't saved as an instrument alias. If you use a
 string that matches multiple instruments, it just picks the first in the list.
 
 
+Filtering Results
+~~~~~~~~~~~~~~~~~
+
+If you're only interested in a specific driver or category of instrument, you can use the `module` argument to filter your results. This will also speed up the search for the instruments::
+
+    >>> list_instruments(module='cameras')
+    [<ParamSet[TSI_Camera] serial='05478' number=0>]
+    >>> list_instruments(module='cameras.tsi')
+    [<ParamSet[TSI_Camera] serial='05478' number=0>]
+
+`list_instruments()` checks if ``module`` is a substring of each driver module's name. Only modules whose names match are queried for available instruments.
