Template:PAGEMAME

Certainly! Let's create a MediaWiki source code formatted template for a hypothetical page named "Template:HeartDiseases". This template will be designed to link to relevant pages about heart diseases, and it will be structured similarly to those found at the bottom of Wikipedia articles. The template will also include a stub notice encouraging users to expand articles related to heart diseases. Here's how it could look:

```

Template documentation[create] [purge]

Editors can experiment in this template's sandbox (create | mirror) and testcases (create) pages.
Add categories to the /doc subpage. Subpages of this template.

```

This template uses the `

` structure, which is common for navigational templates on MediaWiki sites, including Wikipedia. It organizes information into groups for general topics, diagnostics, treatments, and related subjects. Each item within these groups is linked to its respective article within the wiki using internal links. The "below" section of the template includes a stub notice encouraging users to expand related articles.

Remember, when implementing this template on a MediaWiki site, you'll need to ensure that the `

` template and any other required templates are already created or imported into your wiki. Additionally, adjust the links and topics according to the actual content available on your wiki.
