Finalizing installation by "viewing your site in a web browser"?

I followed the instructions for the first time install of WordPress on WPMU and it was great -- until this:
"8. Dragging the code from the WordPress folder on your computer into the root directory of your site uploads the WordPress code to your site." I did that, and didn't see any errors, all the files seemed to move over, etc.

But this never happened: "However it doesn’t complete your WordPress installation. Check this by viewing your site in a web browser – you should now see instructions for finalizing your installation of WordPress."

I went to the domain and the temp ISP domain and got "this is the future home" and nothing else.

What did I do wrong, and how do I fix it?
