Does anyone know how to even start working on this hypothetical problem? Please help!

You are responsible mobile application that delivers news. The app is currently designed to display content one for a page at a time, and requires that the user taps "next" in order to get the next set of news. You've been tasked with converting this experience to one where the user can continuously scroll through the content like a feed. Describe in detail how you would accomplish this, end-to-end (i.e. on the front-end as well as back-end)
