Template documentation[view] [edit] [history] [purge]

This template uses Lua:

Module:High-use (sandbox)

This is the {{used in system}} message box.

It is meant to be put at the top of the documentation for templates and modules that are used in the Wikipedia user interface.

Note! It is normal that some of the links in the message box are red.

Usage[edit]

The template can be used as is. But it can also take some parameters:

First parameter allows you to change the second half of the heading text. See examples below.
Second parameter is the name of some other talk page if you want discussion to be made there instead. But a better option might be to redirect the talkpage of your template to that other talkpage.

Here are some examples:

{{used in system|in many system messages|Wikipedia talk:High-risk templates}}

This template is used in many system messages.
Changes to it can cause immediate changes to the Wikipedia user interface.
To avoid major disruption, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes at Wikipedia talk:High-risk templates before implementing them.
