+## Progress
+This document tracks the progress being made to port over all of the Turf functionality to 
+Dart. This is an on going project and functions are being added once needed. If you'd like to contribute by adding a Turf function that's missing, please open a GitHub issue still with information relative to why you need this functionality.
