+## Cycle - a Javascript implementation of Rails' Text Helper
+
+Built to ease zebra-striping a table. I've avoided any JS library-provided niceties to maximize portability. No support for naming.
+
+Basic usage:
+
+    >>> Cycle.thru('one', 'two', 'three');
+    "one"
+    >>> Cycle.thru('one', 'two', 'three');
+    "two"
+    >>> Cycle.thru('one', 'two', 'three');
+    "three"
+    >>> Cycle.thru('one', 'two', 'three');
+    "one"
+    >>> Cycle.thru('one', 'two', 'three');
+    "two"
+    >>> Cycle.reset('one', 'two', 'three');
+    >>> Cycle.thru('one', 'two', 'three');
+    "one"
