Flash Builder can be used to build any Flash-based applications or content, either using the Flex framework or ActionScript 3.
For examples of Flex applications I'd recommend you take a look at the Flex.org showcase: http://flex.org/showcase

I don't understand. The showcase contains a list of websites. What do you need documentation about ?
