+### Advanced usage
+
+When you are using [SASS](https://sass-lang.com/) (or SCSS) you can also import the `index.scss`, which allows configuration which font families, Unicode ranges and styles should be included as well as from where the font files are loaded.
+
+<!-- prettier-ignore -->
+```scss
+// only include Source Sans 3 and Source Code Pro in the italic-style
+// and latin as well as latin-ext
+@use '@arma-events/web-fonts/dist/index.scss' with (
+  $families: ('Source Sans 3', 'Source Code Pro'),
+  $styles: ('italic'),
+  $ranges: ('latin', 'latin-ext'), // omit $ranges entirely to include all ranges
+);
+```

+> The "possible values" column in the table below might be outdated. Check the `dist/_build_info.scss` file in your package directory for the correct values.
