-Specifying Ranges

+Squib Thinks in Arrays
+======================

+.. _using_ranges:
+
+Using ``range``
+---------------
+
+There's another way to limit a method to certain cards: the ``range`` parameter.
 
 Most of Squib's DSL methods allow a `range` to be specified as a first parameter. This parameter is used to access an internal `Array` of `Squib::Cards`. This can be an actual Ruby range, or anything that implements `#each` (thus can be an `Enumerable`). Integers are also supported for changing one card only. Negatives work from the back of the deck.
