 # NimFunge98 : a Funge-98 interpreter written in nim
 
-This repository contains code for a nim program that can interpret a valid [Funge-98](https://github.com/catseye/Funge-98/blob/master/doc/funge98.markdown) program. It will soon pass the [mycology test suite](https://github.com/Deewiant/Mycology).
