-Semantic-UI integration of font-awesome :
+Fomantic-UI integration of FontAwesome :
 
-///class names are separated
-i.icon.circle => i.icon.circle
-i.icon.circle-o => i.icon.circle.outline
+// class names are separated
+i.icon.angle-left  =>  i.icon.angle.left
 
-//abbreviation are replaced by full letters:
-i.icon.ellipsis-h => i.icon.ellipsis.horizontal
-i.icon.ellipsis-v => i.icon.ellipsis.vertical
-.alpha => .i.icon.alphabet
-.asc => .i.icon.ascending
-.desc => .i.icon.descending
-.alt =>.alternate
+// variations are extracted
+i.icon.circle      =>  i.icon.circle
+i.icon.circle-o    =>  i.icon.circle.outline
 
-ASCII order is conserved for easier maintenance.
+// abbreviation are replaced by full words
+i.icon.*-h         =>  i.icon.*.horizontal
+i.icon.*-v         =>  i.icon.*.vertical
+i.icon.alpha       =>  i.icon.alphabet
+i.icon.asc         =>  i.icon.ascending
+i.icon.desc        =>  i.icon.descending
+i.icon.alt         =>  i.icon.alternate
 
-Icons that only have one style 'outline', 'square' etc do not require this class
-for instance `lemon icon` not `lemon outline icon` since there is only one lemon
+
+Icons are order A-Z in their group, Solid, Outline, Thin (Pro only) and Brand
