This is a documentation subpage for Template:!((. It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 468,000 pages, or roughly 1% of all pages. To avoid major disruption and server load, 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. Consider discussing changes on the talk page before implementing them.

This template is used to place the square brackets [[ onto the page. This is usually done to mitigate the conflict between template syntax and wikilink syntax; in other words, to put complex parser functions inside of the brackets of a wikilink. It is mirrored by {{ ))!}}, which will place the closing square brackets ]] and complete the wikilink.
