How can I get started making an intro to a website in flash?

I'm interested in eventually getting to the level of mbusa.com...but for right now... how can I start with just a flash intro?|||yes, but you pretty much need the Adobe Flash software to create pages in flash. Once you create your intro you can link it to your main page using a "get URL" command linked to your timeline or a button, depending on how you want it to flow.
