+# HQuantLib #
+
+HQuantLib is intended to be a port of [QuantLib](http://quantlib.org) in Haskell. It is not one-to-one port of the library but rather it is a re-implementation of ideas leveraging current libraries available in Haskell Platform.
+
+The latest version implements:
+
+1. Currencies (major only)
+2. Time: Thirty360 DayCounter
+3. Base 1D stochastic processes: Geometric Brownian, generic Ito process, square-root, Ornstein-Uhlenbeck, generalized Black-Scholes
+4. Instruments: Bonds and Stocks
+5. Monte Carlo engine for 1D processes
+6. Volatility estimators: simple local estimator, Garman-Klass simple sigma and Parkinson sigma.
+7. Copulas : Clayton, Max, Min, Ali-Mikhail-Haq and Farlie-Gumbel-Morgenstern
+
+# Version 0.0.4.0 #
+Monte Carlo engine has been moved to new Haskell-native RNG.
