Help:Template
A template is a page anyone can create. An example template is Template:Stub. If someone creates an article that belongs in a certain category, they can add the template name for that category by adding the template name in double brackets at the bottom of the page, like so: Template:Category name. For example, this page has the the template {{Tutorial}} at the bottom of the page.
A category is a page where all articles with a similar theme are listed. An example is. All articles that were categorized with the {{stub}} formatting will be in this category. To directly add a page to a category, use the [[Category:Insert Category]] code. This page, for example, displays the [[Category:AoPSWiki]] code at the bottom.
To create a template, which we will call "Sample" for the purposes of this tutorial, first navigate to the page Template:Sample. Edit the page, then add the following text (anything in bold can be changed):
This article is a sample. It's purpose is to do this and that and this that.
<noinclude>''This template will categorize articles that include it into [[:Category:Stubs]].''</noinclude>
[[Category:Stubs]]
