Templates are pages in the template namespace. This means any page beginning with "Template:", such as [[Template:Templatename]] can be used as a template. The content of a template can be added to a page by typing {{templatename}}.

Templates are used to add recurring messages to pages in a consistent way, to add boilerplate messages, to create navigational boxes and to provide cross-language portability of texts.

Creating, editing and using templates

You start a new template in the same way you would start an article page. The only difference is that its title must start with Template:.

Once you have made the template, you can add {{templatename}} to the pages you want to use it on. Every page using this template will get the same boilerplate text, each time a user visits it. When the template is updated, all pages containing the template tag will be automatically updated.

Watch a video demonstration of how to add a template to a page.

Alternatively, you can add {{subst:templatename}} to the pages you want to use the boilerplate text on. The system will fetch a one-time copy of the template text and substitute it into the page, in place of the template tag. If anyone edits the template afterwards, pages that used the subst: keyword will not be updated. Sometimes that's what you want.

If the template you want to edit looks like {{foo}}, you would go to Template:Foo to edit it. To get there, type in the URL to your address bar, search for it, or make a link in the sandbox and click on it.

Once you are there, just click "edit" or "edit this page" and edit it in the same way you would any other page. You can add anything you would add to a normal page, including text, images and other templates. Please be aware that your edit might affect many pages, so be cautious.

FAQ

Can I use a template in more than one project? 
No, if you want to use it on two different language Wikipedias, for example, you would need to create it twice.
Are templates case sensitive? 
Yes, except usually the first letter.
Can I add parameters? 
Yes, see Help:Template for instructions.
How many templates can I use in a page? 
As many as you like (in older versions you could not use the same one more than 5 times).
I edited the template, so why didn't the page it is used on change? 
There are some caching bugs. One way to force refresh is to do edit on the page in which the template appears, and to then click on Save page without having changed anything — there is no need to fill in the Summary field since there will not be any history of this as a change generated. Alternatively, refreshing by pressing Ctrl and F5 often helps. Another way is add "&action=purge" to the address, like you would for "&action=edit" (e.g., :index.php?title=foo&action=purge).
Can I move a template to a new name? 
Yes, this works in exactly the same way as normal page moves. When a page called for inclusion is a redirect page, the redirect target is included instead.
Can I use a template within a template? 
Yes.
How do I add a new template?
You start a new template in the same way you would start a normal page. The only difference is that its title must start with Template:.
Where is the manual for the programming language used to write templates?
The language inside templates is the same language as regular wiki markup, but template writers tend to use the more complex available functions such as #if: statements. See mw:ParserFunctions and see the other "advanced functioning" help pages listed below.
