to the end of the template code, making sure it starts on the same line as the code's last character.
The following, however, may be used to make the template more informative:
type
Setting type to one of the following values adds a preset note as to which type of template the category (but not necessarily its subcategories) is meant to contain. The values are:
ambox
campaignbox
conversion
external link
formatting
function
message
meta
navbox
navigation
sidebar
stub
sub
timeline
userbox
If type is set to something other than one of these values, the default "The pages listed in this category are templates" note appears unmodified.
type alone
{{Template category |type=sidebar}}
The pages listed in this category are meant to be sidebar templates.
to the end of the template code, making sure it starts on the same line as the code's last character.
Further examples of type's output appear in the examples below.
topic
Use topic to add a default description ending "...relating to topic", where topic is usually a wikilink to the main article associated with the category (e.g. United States for the Category:United States templates).
to the end of the template code, making sure it starts on the same line as the code's last character.
description
Use description if a customised description is needed instead of – or, if topic also used, to follow – the default description above.
type, topic, description
{{Template category
| type = navbox
| topic = [[China]]
| description = <br />{{small|For templates relating specifically to the [[People's Republic of China|People's Republic of China (PRC)]] or the current [[Republic of China|Republic of China (ROC, "Taiwan")]], see, respectively, {{c|People's Republic of China templates}} and {{c|Republic of China (Taiwan) templates}}.}}
}}
to the end of the template code, making sure it starts on the same line as the code's last character.
onright
Use onright to place right-aligned boxes beside the template such as {{Portal}} (to provide link/s to related portal/s), {{Commons category}} (to provide a link to the same or a similarly-named Commons category), etc. If more than one box is included, ensure the widest one appears first (see example below) otherwise overlapping may occur.
topic, onright
{{Template category
| topic = the [[United States]]
| onright = {{Commons category|United States|the United States}}{{Portal|United States}}
}}
to the end of the template code, making sure it starts on the same line as the code's last character.
container
Set container as true, yes, etc. to identify the category as a container category, i.e. a category meant to contain only subcategories. A note requesting that no templates are added to the template category is then included.
{{Container category}} following {{Template category}}
{{Template category
| type = ''type''
| topic = ''[[topic]]''
| description = This text supplied by the ''description'' parameter.
}}
{{Container category}}
Templates relating to topic. This text supplied by the description parameter.
The pages listed in this category are meant to be type templates.
