 # Ullage
 
-Ullage started as an attempt to implement a top-down operator precedence parser in Rust. It has since started developing into a small language. Feel free to have a poke around but don't expect much to work at the moment.
+A statically-typed compiled language defined by a simple grammar.
 
 ## Current Status
 
-It is now possible to write simple programs. The following program computes 9 factorial:
