Having trouble initializing installation….

Hi,

I am using the current version.

I am trying to redo my website: https://asianadventures.org

I created a sub directory to create the new site:
https://asianadventures.org/test1.asianadventures.org/

I just uploaded the folder to this directory. I thought when I go to the subdirectory
link ( https://asianadventures.org/test1.asianadventures.org/ ) I would be prompted on what to do next, but I wasn’t.

What am I doing wrong?

Thanks
