How can i find demo content?

Hello. I installed the free version. Is it possible to have slider?.
I see is not as the picture i see.

Hi, I’m new to this and building a website for my family chinese restaurant. I’m using the chinese restaurant theme found here

The website is kamscuisinerestaurant.com

The first problem is that I want to place the title lower. Second, the header image doesn’t show up on the main page when I uploaded it. Finally, when I upload images on the different pages on the menu, they all seem to stay on the left side and not fill up the page until moving onto the next row.

When I uploaded the Chineses restaurant theme it did not have what it looked like on the picture. It was a start from scratch. Are files missing?
