 ## Usage
-This is mainly useful at night, when you're switching between light & dark
-themes. Less squinting.
+Do you work late at night with the lights off? Do you squint every time you
+switch between apps with light & dark themes?
+
+**Lux** fixes this problem by automatically adjusting your screen brightness.
+Color samples are taken from your screen & based on that, Lux will automagically
+lighten/darken your screen brightness.
 
 ### Important
-Disable "**Automatically adjust brightness**" in `System Preferences` ->
+While Lux is running you're not able to change your brightness level, simply
+turn off Lux to get back full control.
+
+Make sure "**Automatically adjust brightness**" is disabled, you can find it in `System Preferences` ->
 `Displays`.
