-# Usage 
-Via the instance id you can choose:
-- `instance=short` in every module provides even shorter output without units
-- `instance=swap` in the module `ram` to show swap usage
-- `instance=1` in the module `battery` to show the status of BAT1 of you have more than one battery attached to your device.
+# Usage
+- module *datetime*: A left click will toggle long and short displays. The short version is displayed in the format `HH:MM`. The long version also shows the day of the week, weeknumber, date and seconds.
+- module *audio*: `instance=mic` will show the microphone level instead. With a left mouse click the device is muted/unmuted.
+- module *ram*: by default free ram and swap are shown in the format `a+b G` where `a` is ram and `b` is swap. If you want to show ram and swap seperatly, use `instance=ram` or `instance=swap`. If you left click on the block, `top` will be openend.
+- *cpu*: by default total idle cpu time of all cores together is displayed. If you left click on the block, `top` will be openend.
+- module *battery*: by default the total left energy of all attached batteries is shown. If you want to display the batteries seperatly, use `instance=x` will show the status of BATx in case you have more than one battery attached to your device.
