Enclose a required value or list of required arguments. One or more values or arguments can be specified. For example, in the syntax

use image [primary | secondary]

you must specify either the primary or secondary image when entering the command. Do not type the square brackets.

braces { }

Enclose an optional value or a list of optional arguments. One or more values or arguments can be specified. For example, in the syntax
