-Abstract: This specification defines a method to incrementally transfer fonts from server to client.
-          Incremental transfer allows clients to load only the portions of the font they actually need
-          which speeds up font loads and reduces data transfer needed to load the fonts. A font can
-          be loaded over multiple requests where each request incrementally adds additional data.
+Abstract: This specification defines a method to incrementally transfer a font 
+  from server to client. The client loads only the portion(s) of the font that 
+  they actually need, significantly reducing data transfer. Multiple incremental 
+  additions to the same font are possible, such as a user agent updating a font 
+  as a user browses multiple pages. Incremental transfer improves on 
+  unicode-range by avoiding damage to layout (kerning, ligatures, etc) rules, 
+  meaning it can efficiently support fine grained increments to latin and 
+  to complex scripts like Indic or Arabic.
