-To get started designing web parts, you will need to be familiar with Office UI Fabric. You can use Fabric as a starting point for iconography, font ramp, color usage, animation, and the responsive grid. Building from this foundation is a good starting point even if your goal is to depart visually in order to match your own company’s brand or look and feel.
+To get started designing web parts, you will want to be familiar with [Office UI Fabric](http://dev.office.com/fabric). All of the styles from [Fabric Core](https://github.com/OfficeDev/office-ui-fabric-core) – including icons, typography, color usage, animation, and the responsive grid – are loaded by default and available to your web part. Do not import a copy of Fabric for your web part, as this may conflict with the global copy. These classes provide a foundation to your web part's styling, which you can always depart from if you require different visuals to match your company's brand.
