Module:Infobox
Module documentation​[​view​] [edit] [history] [purge]
This Lua module is used on approximately 3,750,000 pages, or roughly 7% of all pages.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.
This module depends on the following other modules:
Module:Navbar (sandbox)
Module:Infobox is a module that implements the {{Infobox}} template. Please see the template page for usage instructions.
