Cooking Steaks???

I saw part of a post on Pinterest about cooking steaks not on the grill.  It was really interesting but incomplete as the site wouldn’t come up correctly.  It stated to preheat your oven to 500 degrees, cook the steaks in a castiron skillet, and to use fresh steaks from the butcher.  That’s it.  Has anyone tried this?  Folks were raving about them cooked this way saying no more steaks on the grill for them.  Definitely got my interest.   You know how it is with us ‘foodies’ when we can’t get the whole recipe!  LOL!!  Thank you for any input.
