Notumn DecaX Customisation

Anyone has this theme?
I practically trying to achieve the look what’s in the demo: Notumn | A Clean, Elegant & Minimal wordpress theme for bloggers.
But I son’t know what to use for the carousel header, how to force the posts appearing only excerpt (it is already set like that in WP but the full post is appearing instead), how to add social icons at the bottom of the post and how to add avatar/bio

You can contact the item author and ask pre-purchase questions

Thnaks, will drop them a line. I already bought the theme but options are not showing for me that are listed as part of the package. Also some widgets that are suggested with the theme once you uploaded it are gone completely.
