* '''Already cited elsewhere in the article.'''  Infoboxes, like the introduction to the article, should primarily contain material that is expanded on and supported by citations to reliable sources elsewhere in the article. However, if necessary (e.g., because the article is currently incomplete), it is possible to include footnotes in infoboxes.

==What should an infobox not contain?==
In general, data in infobox templates should not have:

* '''Excessive length.'''  Long bodies of text, or very detailed statistics, belong in the article body.
* '''Trivial details.''' A common problem is including material in the infobox which is trivial and would not otherwise be included in the article body: for example, a fictional character's [[Biology:Blood type|blood type]] may be referenced in passing in a work, but it is not especially useful to understanding the subject. Infobox templates should not be used for details that are too trivial to include in the article body (there are some exceptions, such as chemical properties).
* '''Flags.''' Flag icons should generally not be used in infoboxes, even when there is a "country", "nationality" or equivalent field: they are unnecessarily distracting and give undue prominence to one field among many.

==Adding an infobox to an article==

There are two steps required to add an infobox to an article:
#Finding the infobox
#Editing the article

===Finding the infobox===
In order to use an infobox in an article, an editor must know its name, parameters, and how those parameters are intended to be used. Because infoboxes are kept in a namespace separate from articles, it takes some effort to identify an infobox by name. Once the editor has the name, however, it is straightforward to look up the infobox's documentation.

There are two ways in which an editor typically locates which infobox they want to use:
*By browsing the set of all infoboxes via Wikipedia:List of infoboxes.
*By determining the name of a particular infobox used in a similar article.

For example, the article [[Engineering:D-Terminal|D-Terminal]] contains an infobox.  To determine which one, simply edit the article:

<pre>
{{Infobox connector
...
}}
</pre>

The "<CODE>{{Infobox connector</CODE>" identifies the markup between the enclosing braces as a use of the "<code>connector</code>" infobox. The editor can look up the documentation for the template, including a list of parameters, in the Template namespace under Template:Infobox connector.

===Editing the target article===
In accordance with Wikipedia's Manual of Style, infoboxes should be placed at the top of an article after any disambiguation links and maintenance tags.

The infobox documentation page usually contains a convenient "blank" template that can be copied directly into the target article.  The template consists of opening (<CODE>{{</CODE>) and closing (<CODE>}}</CODE>) double braces that contain the name of the infobox and a list of parameters without values.  An editor then fills in the value for each of the parameters to the right of the corresponding equals sign.

For example:

<pre>
{{Infobox person
|name    =
|image   =
|caption =
...
|website =
}}
</pre>

might be filled out like this:

<pre>
{{Infobox person
|name    = Casanova
|image   = Casanova_self_portrait.jpg
|caption = A self portrait of Casanova
...
|website =
}}
</pre>

In this example, the names of the parameters ("<CODE>name</CODE>", "<CODE>image</CODE>", "<CODE>caption</CODE>", "<CODE>website</CODE>") are fixed in the design of the infobox and described in its documentation.  A parameter that is misspelled, falsely capitalized, or is not supported by the infobox implementation does not display at all.  To find out exactly which parameters are functional, look at the infobox's template page.  Anything not listed there will be ignored, even if it works in some other infobox.  If you believe that another parameter needs to be added to a given infobox template, then suggest that on the infobox's talk page.

The infobox documentation describes which parameters are required and which are optional.  Required parameters display between triple braces (for example, <CODE>{{{requiredparametername}}}</CODE>) when previewed or published.  Optional parameters may be left empty or omitted entirely.

===Troubleshooting===
If you added an infobox and it didn't display correctly, here are the common errors:

* You used a made-up or invalid parameter.  You can only use parameters that have been pre-programmed into ''this'' infobox template.
* You misspelled the parameter name or omitted necessary punctuation (e.g., leaving out the [[Underscore|underscore]] in <code>birth_place</code>).
* You capitalized the parameter name.  Parameters are case sensitive.  Nearly all infoboxes use lowercase parameter labels.
* You included the prefix <code>File:</code> before the image name (or you didn't, and it's one of the templates that requires it).
* You used the parameter name more than once: only the final instance displays.

==Adding an image to an infobox==
Images are generally specified using the <CODE>image</CODE> and <CODE>caption</CODE> parameters.  However, the template may use a different name for this parameter.  For example, {{tp|Infobox album}} uses "Cover" instead of "image" and "Caption" instead of "caption".

The <CODE>image</CODE> parameter sometimes requires the Wikipedia:Extended image syntax; other times it requires only the image file name depending on the tastes of the editor who created the infobox.  An editor can determine this either by experimenting (using the "preview" function) or by consulting the infobox template documentation.

Many images in infoboxes should have a special text alternative for people who cannot see the image.

==Combining multiple infoboxes==
If an article requires two or more infoboxes it is often possible to combine them into one, 
by including the others as a module (or child-, or sub-template) of the first. See the linked page for instructions.

==Designing an infobox==
{{for|detailed guidance on how to design infoboxes|Help:Designing infoboxes}}
It is a good idea to seek the opinions of other editors before embarking on a design of a new infobox or redesign of an existing one.  Most requirements are already met by an existing infobox and most of the remainder can be met with a tweak.  Unnecessary duplication leads to clutter and article divergence.  Prototype your new design in your own user space.  Once prototyped, propose the infobox changes to the appropriate WikiProject and gain consensus before deploying your new design in the template namespace.

==Deleting an infobox==
Requests to delete an infobox should be brought to the attention of Wikipedia:Templates for discussion and any WikiProjects associated with the infobox.  A template may be merged with another rather than deleted outright.
