+Instant Runnoff Voting (IRV)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+IRV is a preferential voting system used widely for government elections
+in Australia and New Zealand and elsewhere. IRV asks voters to rank
+candidates in preference and then holds a series of "runoff" elections
+by eliminating the weakest candidate and recomputing the election
+results until there exists a candidate who has a majority of the
+remaining votes.
+
+Example::
+
+ require 'runoff'
+ vote_array = [ ["A", "B"],  ["B", "A"], ["B", "A"] ]
+ resultobject = InstantRunoffVote.new(vote_array).result
