How to load either Flash page or html page?

Hi,
I am new to Flash. I have a webpage made in Flash, a page made in regular html. I want the user to be automatically directed to the html version if they don’t have Flash 8 installed.
I checked out SWFObject but im really confused of what to do. This has been done so many times, there must be an “easy” way to do it. It is javascript code, right? Where do i add the extra code?
Any help would be great!
Thanks,
Dave
