+
+**React Theme Sass for [Fluent UI React](https://developer.microsoft.com/en-us/fluentui)**
+
+SASS variables referencing react-theme design tokens injected to DOM by react-provider.
+
+## Usage
+
+1. Instantiate a `FluentProvider` to inject a Fluent theme into a DOM:
+
+```jsx
+import React from 'react';
+import ReactDOM from 'react-dom';
+import { FluentProvider, teamsLightTheme } from '@fluentui/react-components';
+import App from './App';
+ReactDOM.render(
+  <FluentProvider theme={teamsLightTheme}>
+    <App />
+  </FluentProvider>,
+  document.getElementById('root'),
+);
+```
+
+2. In SCSS styles you can import SCSS variables from `@fluentui/react-theme-sass` and use them in the styles:
+
+```scss
+@import '~@fluentui/react-theme-sass';
+.brandedElement {
+  color: $colorBrandForeground1;
+  background: $colorBrandBackground;
+  border-radius: $borderRadiusLarge;
+}
+```
+
+⚠ This package does not export any Javascript code.️
