Using a standard list controller is very similar to using a standard controller. First you set the standardController attribute on the <apex:page> component, then you set the recordSetVar attribute on the same component.
<apex:page standardController="Account" recordSetVar="accounts">
The recordSetVar attribute not only indicates that the page uses a list controller, it sets the variable name of the record collection. This variable can be used to access data in the record collection.
