Also it seems that creating/building the driver has changed and should be

var driver = await new Builder()
    .forBrowser('firefox')
    .build();

Thanks for the doc update, I really like the new docs. As for the example, it should still be fine as you'd have to decronstruct the WebDriver object to get Builder on it's own, so the example should still work as it is written.

Seems circle never got the message about a new pr... Could you push an empty commit to retrigger the build? git commit -m "trigger build" --allow-empty
