          Hardware Random Number Generator Core infrastructure.
 
          To compile this driver as a module, choose M here: the
-         module will be called rng-core.
+         module will be called rng-core.  This provides a device
+         that's usually called /dev/hw_random, and which exposes one
+         of possibly several hardware random number generators.
+
+         These hardware random number generators do not feed directly
+         into the kernel's random number generator.  That is usually
+         handled by the "rngd" daemon.  Documentation/hw_random.txt
+         has more information.
 
          If unsure, say Y.
