help with index page

[efx]

sorry, i'm new to this kind of control panel
just a quick and probably easy question

when i go to my websites URL, it shows a directory
How do I make it so when I go to the URL, it will automatically load the index?

my website URL is http://efx.x10hosting.com
but in order to go to the index, i have to go to http://www.efx.x10hosting.com/index

can someone please help me out?
thanks~ =]
