Description
This template is used to insert descriptions on template pages.
Syntax
Add <noinclude>{{{{#if:|{{{prefix}}}:}}Documentation{{#if:||<{{{2}}}>}}{{#if:||<{{{3}}}>}}{{#if:||<{{{4}}}>}}{{#if:||<{{{5}}}>}}{{#if:||<{{{6}}}>}}{{#if:||<{{{7}}}>}}{{#if:||<{{{8}}}>}}{{#if:||<{{{9}}}>}}{{#if:||<{{{10}}}>}}{{#if:||<{{{11}}}>}}{{#if:||<{{{12}}}>}}{{#if:||<{{{13}}}>}}{{#if:||<{{{14}}}>}}{{#if:||<{{{15}}}>}}{{#if:||<{{{16}}}>}}{{#if:||<{{{17}}}>}}{{#if:||<{{{18}}}>}}{{#if:||<{{{19}}}>}}{{#if:||<{{{20}}}>}}{{#if:||<{{{21}}}>}}}}</noinclude> at the end of the template page.
Add <noinclude>{{{{#if:|{{{prefix}}}:}}Documentation{{#if:documentation page||<documentation page>}}{{#if:||<{{{3}}}>}}{{#if:||<{{{4}}}>}}{{#if:||<{{{5}}}>}}{{#if:||<{{{6}}}>}}{{#if:||<{{{7}}}>}}{{#if:||<{{{8}}}>}}{{#if:||<{{{9}}}>}}{{#if:||<{{{10}}}>}}{{#if:||<{{{11}}}>}}{{#if:||<{{{12}}}>}}{{#if:||<{{{13}}}>}}{{#if:||<{{{14}}}>}}{{#if:||<{{{15}}}>}}{{#if:||<{{{16}}}>}}{{#if:||<{{{17}}}>}}{{#if:||<{{{18}}}>}}{{#if:||<{{{19}}}>}}{{#if:||<{{{20}}}>}}{{#if:||<{{{21}}}>}}}}</noinclude> to transclude an alternative page from the /doc subpage.
Usage
On the Template page
This is the normal format when used:
TEMPLATE CODE
<includeonly>Any categories to be inserted into articles by the template</includeonly>
<noinclude>{{Documentation}}</noinclude>
If your template is not a completed div or table, you may need to close the tags just before {{Documentation}} is inserted (within the noinclude tags).
A line break right before {{Documentation}} can also be useful as it helps prevent the documentation template "running into" previous code.
On the documentation page
The documentation page is usually located on the /doc subpage for a template, but a different page can be specified with the first parameter of the template (see Syntax).
Normally, you will want to write something like the following on the documentation page:
==Description==
This template is used to do something.
==Syntax==
Type <code>{{t|templatename}}</code> somewhere.
==Samples==
<code><nowiki>{{templatename|input}}</nowiki></code>
results in...
{{templatename|input}}
<includeonly>Any categories for the template itself</includeonly>
<noinclude>[[Category:Template documentation]]</noinclude>
Use any or all of the above description/syntax/sample output sections. You may also want to add "see also" or other sections.
Note that the above example also uses the Template:T template.
