==Creating a template step-by-step==
===Import Module:Infobox and Module:Param Parse===
<syntaxhighlight lang="lua">
local Infobox = require('Module:Infobox')
local parse = require('Module:Param Parse')
</syntaxhighlight>

===Unpack the frame arguments from the Template===
<syntaxhighlight lang="lua">
local p = {}

function p.main(frame)
	local args = frame:getParent().args
	...
</syntaxhighlight>

===Setup the Module config settings===
<syntaxhighlight lang="lua">
	local config = {
		infobox_name = 'Scenery',
	}
</syntaxhighlight>

===Map your arguments to parsing functions===
{{Main|Module:Param Parse}}
Use the params in [[Module:Param Parse]] to validate and format the data - feel free to create your own new params in [[Module:Param Parse]].
<syntaxhighlight lang="lua">
	local params = {
    	parse.name,
        parse.image,
		{name = 'examine', func = parse.has_content, smw_property = 'Examine'}, -- Custom param
        parse.episode,
 		...
	}
</syntaxhighlight>

===Define an Infobox object===
{{Main|Module:Infobox#new}}
<syntaxhighlight lang="lua">
	local infobox = Infobox.new(config, params, args)
</syntaxhighlight>

===Create your table===
{{Main|Module:Infobox#create}}
<syntaxhighlight lang="lua">
	infobox
		:add_row{
			{tag='th', content=Infobox.param('name'), class='infobox-header', colspan='20'},
		}
		:add_row{
			{tag='td', content=Infobox.param('image'), class='infobox-image', colspan='20'},
		}
		:pad(20)
		:add_row{
			{tag='td', content='Info', class='infobox-subheader', colspan='20'},
		}
		:pad(20)
		:add_row{
			{tag='th', content='Examine', colspan="6"},
			{tag='td', content=Infobox.param('examine'), colspan="14"},
		}
		:add_row{
			{tag='th', content='[[Episode]]', colspan="6"},
			{tag='td', content=Infobox.param('episode'), colspan="14"},
		}
		...
</syntaxhighlight>


===You're done!===
<syntaxhighlight lang="lua">
	return infobox
end

return p
</syntaxhighlight>

==Functions==
=== Special params ===
You don't need to do anything about these special parameters, but they may be used as parameters within the Template:
{| class="wikitable"
! param
! explanation
|-
| version1, version2, version3
| Button label and SMW name for each switch version of the infobox
|-
| default_version
| The default version to display when the page is loaded
|-
| version
| If there is only a single version, you can use version to set the SMW name (default SMW name is "DEFAULT")
|}

=== Referring to params ===
Each parameter can have a different value for each version. In addition, there are 3 different representations of each value. Therefore, a parameter must be accessed via one of the 3 helper functions:
{| class="wikitable"
! helper function
! example
! explanation
|-
| Infobox.raw_param(name)
| "1000"
| Raw value as passed by the Template
|-
| Infobox.param(name)
| "1,000"
| Value formatted for display in the Infobox
|-
| Infobox.smw_param(name)
| 1000
| Value formatted to be saved as an SMW property
|}

=== Infobox.new(config, params, args) ===
Creates a new infobox. Automatically parses the arguments, creates SMW subobjects and adds categories.
<syntaxhighlight lang="lua">
	local infobox = Infobox.new(config, params, args)
</syntaxhighlight>
==== config ====
There are only 2 parameters for config
<syntaxhighlight lang="lua">
	local config = {
    	infobox_name = 'Scenery', -- mandatory unique identifier for css
    	max_buttons = 6, -- optional, defaults to 6, max number of switch buttons before using a dropdown list instead
	}
</syntaxhighlight>

==== params ====
A list of parameters to be processed by the Infobox module
<syntaxhighlight lang="lua">
	local params = {
		{ name = <param>, func = <func>, ... },
		...
	}
</syntaxhighlight>


{| class="wikitable"
! key
! value
|-
| name
| parameter name as used in the Template
|-
| func
| A function in [[Module:Param Parse]] to validate and process the Template argument. You can also use a local function, but this is not recommended.
If func is a function, will call func(Infobox.raw_param(name)):
<syntaxhighlight lang="lua">
	{name = <param>, func = <func>, ... },
</syntaxhighlight>
If func is a table, it takes the following parameters:
<syntaxhighlight lang="lua">
	{name = <param>, func = { name = <func>, params = <func_params>}, ... },
</syntaxhighlight>
{| class="wikitable"
| name
| function in [[Module:Param Parse]]
|-
| params
| a list of parameters to pass the the function, in the form of constants, or Infobox.raw_param(name), Infobox.param(name), Infobox.smw_param(name)
|}
|-
| empty (optional)
| text to display in the infobox if func returns nil; defaults to "? (edit)"
|-
| category_never (optional)
| category to add if func returns nil for all versions
|-
| category_partial (optional)
| category to add if func returns nil for some versions, but a value for other versions
|-
| category_incomplete (optional)
| category to add if func returns nil for at least 1 version (i.e. category_never and category_partial combined)
|-
| category_complete (optional)
| category to add if func returns a value for all versions
|-
| smw_property (optional)
| if this string is defined, the parameter will be saved into SMW
|-
| smw_func (optional)
| function to validate and process the Template argument to save into SMW. func is used by default if smw_func is not defined
|}

==== args ====
Arguments passed via the Template
<syntaxhighlight lang="lua">
	local args = frame:getParent().args
</syntaxhighlight>

=== infobox:is_param_defined(param) ===
Used to conditionally display a line in the infobox

<syntaxhighlight lang="lua">
	infobox:add_row{
		{tag='th', content=Infobox.param('name'), class='infobox.subheader', colspan='2'},
	}
	if infobox:is_param_defined(Infobox.param('owner')) > 0 then
		infobox:add_row{
			{tag='td', content='[[Owner]]'},
			{tag='td', content=Infobox.param('owner')},
		}
	end
</syntaxhighlight>
{| class="wikitable"
| param
| a parameter referenced via Infobox.raw_param(name), Infobox.param(name) or Infobox.smw_param(name)
|-
| Returns
| 0 if param is never defined
1 if param is defined for a fraction of the versions

2 if param is defined for all versions
|}

=== Infobox:add_row(...) ===
Adds a row to the infobox table. Parameter should be a table of cells:
<syntaxhighlight lang="lua">
	infobox:add_row{
		{tag='td', content='[[Cell1]]', ...},
		{tag='td', content=Infobox.param('param'), ...},
		{tag='td', content='[[Cell3]]', ...},
        ...
        addClass = 'row-class'
	}
</syntaxhighlight>
Each cell should have a set of key-values, of which only the tag and content are mandatory:
{| class="wikitable"
! key
! value
|-
| tag
| 'td' or 'th'
|-
| content
| a string or Infobox.param(name), Infobox.raw_param(name), Infobox.smw_param(name)
|-
| attr (optional)
| a table of attributes to add to the cell
mw.html:attr({ arg1 = '1', ... })
|-
| css (optional)
| a table of css to add to the cell
mw.html:css({ arg1 = '1', ... })
|-
| class (optional)
| a string with a class to add, or a table of classes to add. '''infobox-header''', '''infobox-subheader''' and '''infobox-image''' are commonly used.
mw.html:addClass(...)
|-
| rowspan (optional)
| Set the cell rowspan
mw.html:attr('rowspan',arg)
|-
| rowspan (optional)
| Set the cell colspan
mw.html:attr('colspan',arg)
|-
| title (optional)
| Set the cell title
mw.html:attr('title',arg)
|}


=== Infobox:pad(colspan, class) ===
Adds a blank row of padding spanning the given number of columns. Will always add the class '''infobox-padding''', but can optionally add another class:
<syntaxhighlight lang="lua">
	infobox:pad("10", class=<class>)
</syntaxhighlight>


=== Infobox:addClass(class) ===
Adds a class to the entire table
<syntaxhighlight lang="lua">
	infobox:addClass(class)
</syntaxhighlight>
