+  This document uses some terminology common to the RISC-V community
+  that is not widely used, the definitions of which are listed here:
+
+  hart: A hardware execution context, which contains all the state
+  mandated by the RISC-V ISA: a PC and some registers.  This
+  terminology is designed to disambiguate software's view of execution
+  contexts from any particular microarchitectural implementation
+  strategy.  For example, an Intel laptop containing one socket with
+  two cores, each of which has two hyperthreads, could be described as
+  having four harts.
