'''Transclusion''' is the core concept that powers '''templates''' in MediaWiki. It allows content from one page (usually a template) to appear dynamically on another page—without having to copy and paste it. Isn’t that cool?

== What is Transclusion? ==
Templates are like '''reusable building blocks'''. Instead of repeating the same information across multiple pages, you define it once in a template and insert it wherever it's needed.

Think of it like a '''function in code''':

<pre>
{{TemplateName}}
</pre>

This one simple line pulls in the entire content of the <code>Template:TemplateName</code> page.

Need to update a banner or a layout on 100 pages? Just update the template—it’ll reflect everywhere instantly. Efficient, consistent, and easy to maintain.

== Basic Usage ==

To transclude a template onto a page, just type:

<pre>
{{ExampleTemplate}}
</pre>

To pass parameters:

<pre>
{{ExampleTemplate|name=Fen|type=Admin}}
</pre>

In the template code itself, you would use:

<pre>
'''User:''' {{{name}}}
'''Role:''' {{{type}}}
</pre>

== Transcluding Other Pages (Not Just Templates!) ==

You can even transclude the content of any regular page:

<pre>
{{Help:Editing}}
</pre>

But be careful—this can create unexpected side effects if used outside of documentation or meta pages.

== Nesting Templates (Templates Using Other Templates) ==

Templates can also '''transclude other templates'''. This is known as '''nesting''', and it allows complex templates to be broken down into smaller, reusable components.

For example, a template like <code>Template:Userbox</code> might call another template like <code>Template:Userbox/core</code> to handle its layout:

<pre>
{{Userbox/core
| border-c = #aaa
| id = Example
| info = This is a nested template
}}
</pre>

This keeps logic separated and easier to maintain. It also enables shared styling or behavior across many templates without repeating code.

== Why Use Transclusion? ==

* ✅ Centralized maintenance
* ✅ Uniform formatting
* ✅ Clean, readable wikitext
* ✅ Dynamic content reuse

== What It’s Not ==

* It’s '''not''' copying and pasting content.
* It’s '''not''' permanent—changes in the source reflect everywhere.
