+instances adhere to the set of laws that they are supposed to.  There are
+other libraries that do similar things, such as @code{genvalidity-hspec} and
+@code{checkers}.  This library differs from other solutions by not introducing
+any new typeclasses that the user needs to learn.  /Note:/ on GHC < 8.5, this
+library uses the higher-kinded typeclasses (@code{Data.Functor.Classes.Show1},
+@code{Data.Functor.Classes.Eq1}, @code{Data.Functor.Classes.Ord1}, etc.), but
+on GHC >= 8.5, it uses @code{-XQuantifiedConstraints} to express these
+constraints more cleanly.")
