+      Dosis is a very simple, rounded, sans serif family.
+
+      The lighter weights are minimalist. The bolder weights have more
+      personality. The medium weight is nice and balanced. The overall result is
+      a family that's clean and modern, and can express a wide range of
+      voices & feelings.
+
+      It comes in 7 incremental weights: ExtraLight, Light, Book, Medium,
