 ### Advanced Usage
 If you want to have a minimal bar that stays out of the way, you can use the `-a` or `--autohide` switch to specify a list of module names. All those modules will only be displayed when (and as long as) their state is either warning or critical (high CPU usage, low disk space, etc.). As long as the module is in a "normal" state and does not require attention, it will remain hidden.
+Note that this parameter is specified *in addition* to `-m` (i.e. to autohide the CPU module, you would use `bumblebee-status -m cpu memory traffic -a cpu`).
