-Safe Mutable History
+Changeset Evolution Experimentation
 ========================================
 
 
+This is the online documentation of the `evolve extension`_. An experimental
+extension that drive the implementation of the `changeset evolution concept`_ for
+Mercurial.
+
+.. _`evolve extension`: http://mercurial.selenic.com/wiki/EvolveExtension
+.. _`changeset evolution concept`: http://mercurial.selenic.com/wiki/ChangesetEvolution
+
 Here are various materials on planned improvement to Mercurial regarding
 rewriting history.
