     As an example, here is how you can simulate rolls of a six-sided die using
     'System.Random.Stateful.uniformRM':
     .
-    >>> let rollM = uniformRM (1, 6)                 :: MonadRandom g s m => g s -> m Word8
+    >>> let rollM = uniformRM (1, 6)                 :: StatefulGen g s m => g s -> m Word8
     >>> let pureGen = mkStdGen 42
     >>> runGenState_ pureGen (replicateM 10 . rollM) :: m [Word8]
     [1,1,3,2,4,5,3,4,6,2]
     .
     The monadic adapter 'System.Random.Stateful.runGenState_' is used here to lift
     the pure pseudo-random number generator @pureGen@ into the
-    'System.Random.Stateful.MonadRandom' context.
+    'System.Random.Stateful.StatefulGen' context.
     .
     The monadic interface can also be used with existing monadic pseudo-random
     number generators. In this example, we use the one provided in the
     <https://hackage.haskell.org/package/mwc-random mwc-random> package:
     .
     >>> import System.Random.MWC as MWC
-    >>> let rollM = uniformRM (1, 6)       :: MonadRandom g s m => g s -> m Word8
+    >>> let rollM = uniformRM (1, 6)       :: StatefulGen g s m => g s -> m Word8
     >>> monadicGen <- MWC.create
     >>> (replicateM 10 . rollM) monadicGen :: m [Word8]
