 **This is currently only possible with an exported JavaScript configuration.**
 
-The basic usage outlined above, will enforce that properties are **strictly** sorted within their groups (box, border, background etc). Given this configuration makes use of [stylelint-order](https://github.com/hudochenkov/stylelint-order/tree/5.0.0) under the hood, there's a couple extra bits of functionality that can be configured. This will require manually generating the configuration - but passing in extra options as seen fit. These will be applied to **each** property group.
