 ## Differences
 
 In Kendo UI, the SASS-based themes demonstrate the following differences from the LESS-based ones:
 
 - Each SASS-based theme is represented by a single CSS file that combines the layout and the themes of the components. As a result, you do not need to match a theme with its common file.
 - Based on the widget you work with, the SASS-based themes can build a part of the widget theme in a similar way the Download Builder trims unused scripts.
-- The SASS-based themes are available on NPM. Each theme is available as an NPM package and can be easily upgraded.
-- Each SASS-based theme is compatible with the [Kendo UI for Angular 2](http://www.telerik.com/kendo-angular-ui/) components. This enables you to port parts of your application to Angular 2 while maintaining their styling.
