Front page components

I am trying to work with the Brimstone theme. On the live demo, it shows that the front page is capable of quite a number of components, such as the display of blog posts, our story, and a “shop seeds” sales type of component. But when I installed the theme the front page only seems to display home page and not allowing any other customization. Is there a way to make the home page capable of displaying multiple components?

Finally, I have tried to put “Chestnut Writers” after “Site crafted with care by” on the footer but it doesn’t show Chestnut Writers at all.

Thank you in advance for your help.
