+# Cyclone Redis Demo
+
+See [github/firoix/cyclone] for the latest source.
+
+## About
+
+This demonstrates integrating [pycket] with [cyclone], using a redis backend (but easily switched to using memcached).
+
+[Cyclone] is a clone of facebook's [Tornado], on top of [Twisted].
+
+Although cyclone and tornado are very similar, cyclone leverages all
+enterprise class features of Twisted, and more. It is extremely stable, and
+ready for production.
