   * `Plot Speed` plots speed over time
   * `Plot HRM` plots heart rate over time
 
+## Usage in code
+
+As long as widgets are loaded, you can:
+
+* Call `WIDGETS["recorder"].setRecording(true)` to start recording (it returns a promise, and may show a menu)
+* Call `WIDGETS["recorder"].setRecording(true, {force:"new"/"append"/"overwrite")` to start recording (it returns a promise, and will not show a menu)
+* Call `WIDGETS["recorder"].setRecording(false)` to stop recording

 ## Tips
 
 When recording GPS, it usually takes several minutes for the watch to get a [GPS fix](https://en.wikipedia.org/wiki/Time_to_first_fix). There is a red satellite symbol, which you will see turn green when you get an actual GPS Fix. You can [upload assistant files](https://banglejs.com/apps/#assisted%20gps%20update) to speed up the time spent on getting a GPS fix.
