not a developer…please dumb down

can you please provide an example of how I would insert shortcode into a page to display app data.

For example, if I wanted to display data on a single app – would I get the app id and then somehow place a code on the page?

Also, is there a way to display multiple items for a genre, or specific search within a genre?

thank you for any help.
