+# Prerequisites
+For this widget to work and to get data from the phone, you need:
+- An Android phone
+  - with xDrip and the <a href="https://codeberg.org/phrogg/BG2BangleJSApp/" target="_BLANK">helper app</a> installed.
+  - the <a href="https://f-droid.org/en/packages/com.espruino.gadgetbridge.banglejs/" target="_BLANK">Gadgetbridge app (bangle version)</a> for the Android phone 
+- A BangleJS
+  - With this widget installed
+
+# Widget
+
+## How to use it
+Make sure you have all the prerequisites from above.
+
+The watch should automatically start displaying values, if there is an arrow visible behind the value, the value is within the not-expired-yet time range changeable in the settings standard is 15 minutes. (I will probably change this in the future, to strike through the text to make expired values clearer).
+
+## Settings
+In the settings, you can:
+- Disable/hide the widget
+- Change the unit from mmol/L to mg/dL
+- Set a time at which old BG values expire
+
+
+# Developer
+Developed by Phil Roggenbuck (<a href="https://github.com/phrogg" target="_BLANK">phrogg</a>)
+
+
+# Disclaimer
+As well as xdrip you should not use this app to make medical decisions!
