A Texinfo file is usually structured like a book with chapters, sections, subsections, and the like. This structure can be visualized as a tree (or rather as an upside-down tree) with the root at the top and the levels corresponding to chapters, sections, subsection, and subsubsections.
Here is a diagram that shows a Texinfo file with three chapters, each with two sections.

Section Section Section Section Section Section
1.1 1.2 2.1 2.2 3.1 3.2
In a Texinfo file that has this structure, the beginning of Chapter 2 would be written like this:
@node Chapter 2 @chapter Chapter 2
For purposes of example, here is how it would be written with explicit node pointers:
@node Chapter 2, Chapter 3, Chapter 1, Top @chapter Chapter 2
The chapter structuring commands are described in the sections that
follow; the @node command is described in
the previous chapter (see Nodes).
