 # fluxgui
 
+The f.lux indicator applet fluxgui is an indicator applet to control xflux, an application that makes the color of your computer's display adapt to the time of day: warm at night, and like sunlight during the day. Reducing blue light exposure in the evening can help you fall asleep at night. See https://justgetflux.com/research.html for more details.
