New to grav problems accessing locally

I’m using Debian for my OS.

I downloaded the latest zip file and moved the extracted folder to /var/www/html

When I go to my web browser and type my IP address The Apache page displays with no problem. However if I type in my browser, admin is appended after grav. Am I doing something wrong?

I am currently using Wordpress and am looking for a simpler alternative. Your help is greatly appreciated!!!
