+
+Implemented:
+
+- Basic medical alert logo and message
+- Only display bottom widget on clocks
+- High contrast colours depending on theme
+
+Future:
+
+- Configure when to show bottom widget (always/never/clocks)
+- Configure medical alert text

+# Twenties
+
+Follow the [20-20-20 rule](https://www.aoa.org/AOA/Images/Patients/Eye%20Conditions/20-20-20-rule.pdf) with discrete reminders. Your BangleJS will buzz every 20 minutes for you to look away from your screen, and then buzz 20 seconds later to look back. Additionally, alternate between standing and sitting every 20 minutes to be standing for [more than 30 minutes](https://uwaterloo.ca/kinesiology-health-sciences/how-long-should-you-stand-rather-sit-your-work-station) per hour.
+
+## Usage
+
+Download this widget and, as long as your watch-face supports widgets, it will automatically run in the background.
+
+## Features
+
+Vibrate to remind you to stand up and look away for healthy living.

+## Creator
