Template:In category/doc

本模板用於某個模板的說明文件。It produces a hatnote that specifies into which category the documented template is categorised.

Basic usage is along the lines of {{In category|Candidates for speedy deletion}}, which produces the following message:

本模板將歸類至Category:Candidates for speedy deletion。

It is possible to specify more than one category, e.g. {{In category|Candidates for speedy deletion|Candidates for speedy deletion by user}} produces:

本模板將歸類至Category:Candidates for speedy deletion 和 Category:Candidates for speedy deletion by user。

Up to five categories are supported.

To override the "and" with another conjunction, use the |and= parameter.
For example, {{In category|Candidates for speedy deletion|Candidates for speedy deletion by user}} would produce:

本模板將歸類至Category:Candidates for speedy deletion or Category:Candidates for speedy deletion by user。

This template does nothing to change the functionality of the documented template: in particular, it will not actually apply the categories. Its purpose is simply to produce a note about what the documented template does, but you will need to implement the template's actual functionality separately.
