           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.
