 ## Quick start options
 
+**It is important to note that logging is turned off by default in v1.13.0 onwards.**
+To turn logging on for development, you will want to run
+`Plotly.setPlotConfig({ logging: 2 })` before any plotting.
+See [this file](https://github.com/plotly/plotly.js/blob/master/src/lib/loggers.js) for more details.
