I purchased the framework theme expecting it

Hi, I purchased the framework theme expecting it to be a complete theme. However it indicates I need to use child theme with it. How do I setup a child theme, or was a child theme file supposed to be downloaded with this that i'm missing? I'm not a developer but was hoping with proper support I could get this fixed. Live support was sending me to offsite instructions on how to code child theme. This is just not the simple plugin that is advertised so I'm confused. Any help is appreciated. THANKS
