 # VMC: a Library for Verified Monte Carlo Algorithms
 
-The `DafnyVMC` module introduces utils for probabilistic reasoning in Dafny. At the moment, the API is intentionally limited in scope, and only supports compilation to C# and Java. For the future, we plan to extend both the functionality and the range of supported languages.
