 * Uses mylocation.json from MyLocation app to calculate sunrise and sunset times for your location
 * If your Sunrise, Sunset times look odd make sure you have setup your location using
 [MyLocation](https://banglejs.com/apps/?id=mylocation)
-* The screen is updated every minute to save battery power
+* The screen is updated every minute to save battery power, unless the ring is set to display seconds, then it updates every 5 seconds.
 * Uses the [BloggerSansLight](https://www.1001fonts.com/rounded-fonts.html?page=3) font, which if free for commercial use
 * You need to run >2V22 to show the battery estimate in hours
+* In the settings, the ring can be set to:
+  *  Hours - Displays the ring as though it's the hour hand on an analog clock.
+  *  Minutes - Displays the ring as though it's the minute hand on an analog clock.
+  *  Seconds - Displays the ring as though it's the seconds hand on an analog clock.
+  *  Steps - Displays the ring as the amount of steps taken that day out of 10,000.
+  *  Battery - Displays the ring as the amount of battery percentage left.
+  *  Sun - Displays the ring as the amount of time that has passed from sunrise to sunset in the day and the amount of time between sunset and sunrise at night.
 
 ## Future Development
 * Use mini icons in the information line rather that text
