The ‘Top’ node is the node in which a reader enters an Info manual. As such, it should contain a very brief description of the manual (including the version number). The contents of the ‘Top’ node do not appear in printed output nor in DocBook output.
It is conventional to write a line with a @top command
containing the title of the document immediately after the
@node Top line (see The @top Sectioning Command).
We repeat the short description from the beginning of the ‘@copying’ text, but there’s no need to repeat the copyright information, so we don’t use ‘@insertcopying’ here.
In the Info output (and sometimes HTML output), the ‘Top’ node usually
contains a top-level menu listing the chapters, and possibly a
detailed menu listing all the nodes in the entire document. It
is not usually necessary to give such a menu in the Texinfo source, as
texi2any generates these menus automatically. However, the
following example shows how you would use the @menu command to
give a menu in the ‘Top’ node:
@node Top @top Short Sample This is a short sample Texinfo file.
@menu
* First Chapter:: The first chapter is the
only chapter in this sample.
* Index:: Complete index.
@end menu
