Adding a new .html to an existing web page Options

[Gardenmega]

Hey guys, first time poster here. I have some knowledge when it comes to designing a web site and I am stumped.

A little background behind what I am trying to do is to help a friend. My friend's grandpa has a website that is hosted on godaddy.com and he wants this one webpage to appear before the main webpage gets displayed. I can easily do this by utilizing their built in URL redirect. My issue comes in when adding this new .html page to the existing directory. The index file is index.php while the file I want to add is People.html. So once I add it to the directory it should then just be <domain>.com/People right? or am I wrong? Once I get this situated, I will just redirect to that page and be done... This may be an easy fix, but I am lost.

Please help.

Thank you,
