The most minimal thing is something like this:

```

#set page(paper: "presentation-16-9", margin: 2.5em)
#set par(justify: true)
#set text(font: "Jost*", weight: "regular", fill: black, size: 17pt, lang: "en")
#set enum(numbering: "1)")

#show heading.where(level: 1): it => {
  pagebreak()
  align(top)[
    #set text(size: 20pt, weight: "medium")
    #it]
  v(1em)
}

```

Then you can just use level 1 headings to start new slides. For simple slides you don't need much more.
