Documentation for this module may be created at Module:Documentation/doc

-- This module implements {{documentation}}.

-- Configuration
----------------------------------------------------------------------------

-- Here you can set the values of the parameters and messages used in this module, so that it
-- can be easily ported to other wikis.

local cfg = {}

-- Argument names
-- The following are all names of arguments that affect the behaviour of {{documentation}}.
-- The comments next to the configuration values are the effects that the argument has
-- on the module. (Not the effects of the argument names themselves.)

cfg.headingArg = 'heading' -- Custom heading used in the start box.
cfg.preloadArg = 'preload' -- Custom preload page for creating documentation.

cfg.contentArg = 'content' -- Passes documentation content directly from the {{documentation}} invocation.
cfg.linkBoxArg = 'link box' -- Specifies a custom link box (end box) or prevents it from being generated.

-- Software settings
-- The following are software settings that may change from wiki to wiki. For example, the classes
-- defined in commons.css or the names of templates.

-- Display settings
-- The following settings configure the values displayed by the module.
