Xconq includes extensive online help. The keyboard command `?' is available in all versions; some interfaces may also include a button or menu item that leads you to the help system. Help information consists of a list of help nodes, each of which describes an aspect of the game or of Xconq in general. There is usually a table of topics that you can select from, or else you can go forwards and backwards through the nodes. The topics include information about commands, the game overall, individual units, scientific advances, and so forth.
