@@ -6,17 +6,15 @@ This is a work-in-progress app, so you may expect missfeatures, bugs and heavy
 battery draining. There's still a lot of things to optimize and improve, so take
 this into account before complaining :-)
 
-* Lat/Lon hardcoded to Barcelona, but it's configurable if you install the "mylocation app"
+* Requires to configure the location in Settings -> Apps -> My Location
 * Shows sea level and make the sun/moon glow depending on the x position
 * The sinus is fixed, so the sea level is curved to match the sunrise/sunset positions)
 
 ## TODO
 
-* Access GPS on first start to cache lat+lon to compute sunrise/sunset times
-* Cache constant values once
-* Show month and day too?
-* Improved gradients
+* Improved gradients and add support for banglejs1
 * Faster rendering, by reducing sinus stepsize, only refreshing whats needed, etc
+* Show red vertical lines or dots inside the sinus if there are alarms
