How to switch to Root Directory

I’ve installed Grav (successfully), at /public_html/grav.

When I hit mydomain[dot]com/grav, the grav pages loads up fine. However, when I hit the mydomain[dot]com - the default page in my root (public_html) loads up. (lets call it index.html)

Can I not have mydomain[dot]com just load up mydomin[dot]com/grav/ ?

Because if I build my site, the /grav/ is showing up in all the URLs.

If possible, move the contents of the grav folder directly into public_html, making Grav your main site.
