+## Usage
+
+There're several files in the `css/` subdirectory. Import them in your project
+to have access to "Roboto" font face:
+
+* `roboto-fontface.css` - whole font family compiled to CSS
+* `roboto-fontface.scss` - whole font family in SCSS
+* `roboto-fontface.less` - whole font family in LESS
+
+Importing whole family may be unnecessary and lead to huge build, so if you are
+using SCSS or LESS, you can import only individual weights by importing one
+of the following files:
+
+* `roboto-fontface-(thin|light|regular|medium|bold|black).scss`
+* `roboto-fontface-(thin|light|regular|medium|bold|black).less`
+
+Their italic variants can be imported by adding `-italic` suffix:
+
+* `roboto-fontface-(thin|light|regular|medium|bold|black)-italic.scss`
+* `roboto-fontface-(thin|light|regular|medium|bold|black)-italic.less`
+
 ## Hinting
 
 Some of the included font files have [hinting](http://en.wikipedia.org/wiki/Font_hinting).
