Completely lost taking a hash and inserting into an array contained within a second hash

I'm really stuck with this code challenge. I have reviewed the videos several times and checked the instructor notes but really don't understand how to complete this challenge?

I believe that i may need to use the .push method but i could be wrong, can someone please help?

shopping_list.rb 
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }

Hi Craig,

Yes you do want the push method. Make sure you select items when you do it. e.g.

grocery_list['items'].push(grocery_item)
