-       Variations on Kirby & Paris' hydra battles and other
-       entertaining math in Coq (collaborative, documented, includes
-       exercises)
+      An exploration of some properties of Kirby and Paris' hydra
+      battles, with the help of the Coq Proof assistant. This
+      development includes the study of several representations of
+      ordinal numbers, and a part of the so-called Ketonen and Solovay
+      machinery (combinatorial properties of epsilon0).
