Can't get Chromium Browser to autostart

Hi,

Will make my apologies now but I am quite new to the Pi scene.
I am trying to get a display screen solution together, I would like the Pi to display a webpage on boot with little else running.
I have downloaded diet pi and tried to get Chromium to autostart without desktop. This is not working, if I peform dietpi-software Chromium is not in the list to install as described it should be. If I do a dietpi-software list | grep disabled then I see chromium as +desktop disabled for g_hw_arch
I am running this on a raspberry Pi 2 which I believe is compatible unless I am missing something?
Any help would be appreciated thanks.
