TLDR

Start reading top-level directory menu

$ info

Start reading at given menu item node from top-level directory

$ info [menu_item]

Start reading at second menu item within first menu item manual

$ info [first_menu_item] [second_menu_item]

Frequently-used options:

-a, --all: use all matching manuals
-k, --apropos=STRING: look up STRING in all indices of all manuals
-d, --directory=DIR: add DIR to INFOPATH
-f, --file=MANUAL: specify Info manual to visit
-h, --help: display this help and exit
--index-search=STRING: go to node pointed by index entry STRING
-n, --node=NODENAME: specify nodes in first visited Info file
-o, --output=FILE: output selected nodes to FILE
-O, --show-options, --usage: go to command-line options node
--subnodes: recursively output menu items
-v, --variable VAR=VALUE: assign VALUE to Info variable VAR
--version: display version information and exit
-w, --where, --location: print physical location of Info file

The first non-option argument, if present, is the menu entry to start from; it is searched for in all 'dir' files along INFOPATH. If it is not present, info merges all 'dir' files and shows the result. Any remaining arguments are treated as the names of menu items relative to the initial node visited.

For a summary of key bindings, type H within Info.
