After importing demo how to choose and arrange?

Overwhelmed with so many pages with importing and as there are no images . The whole Demo is not helpful at all
Those brokend images does not make the theme any useful and I am confused.
Eventually, I have to go and see your live site but my question

How am I to choose pages and clean up the rest? Is there any tips ? Is there any video tutorial?

Also at least you could allow images to come in with your demo and simply water mark them , I paid a lot of money for this theme and it has made my life so hard.
