I'm trying to write some text into a NewBox, and I can't figure out how to do this.

The documentation explains how Print is used to write to a box, but the function takes a tcell.Screen which is an interface the Box struct doesn't conform to. Maybe, the example of how to create and use a Box can be expanded to include some text as well?

Hi, Box by itself doesn't allow you to write text into it. It's really just a box with a border and a title and it's used as the superclass for all other primitives.

If you want to add text, you should use TextView. Because TextView implements the io.Writer interface, you can simply print to it:

t := tview.NewTextView()
fmt.Fprintln(t, "Hello, World!")

The Print() functions in the package are used to write directly to a tcell.Screen but this is useful only if you decide to implement your own Primitive where you would implement the Draw() function. For most applications, this is probably not necessary.
