 ## Summary
 
 
-A short summary of the extension/modification.
+Add the Text datatype to the language.
+
+
+The text package for GHC exposes a Text datatype that represents a string.
+
+
+The current String = \[Char\] standard has issues with
+
+- efficiency: there are more efficient representations than linked lists
+- correctness: for Unicode correctness, one must operate on a string as a whole rather than individual code points
+
+
+Promoting Text solves both of these issues.
