| pre-alpha | prealpha | pa = This module is rated as pre-alpha. It is unfinished, and may or may not be in active development. It should not be used from article namespace pages. Modules remain pre-alpha until the original editor (or someone who takes one over if it is abandoned for some time) is satisfied with the basic structure.{{#switch: If empty|doc|sandbox= | {{#ifeq: | true | | }} }} | alpha | a = This module is rated as alpha. It is ready for third-party input, and may be used on a few pages to see if problems arise, but should be watched. Suggestions for new features or changes in their input and output mechanisms are welcome.{{#switch: If empty|doc|sandbox= | {{#ifeq: | true | | }} }} | beta | b = This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.{{#switch: If empty|doc|sandbox= | {{#ifeq: | true | | }} }} | release | r | general | g = This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing.{{#switch: If empty|doc|sandbox= | {{#ifeq: | true | | }} }} | protected | protect | p = 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.{{#switch: If empty|doc|sandbox= | {{#ifeq: | true | | }} }} | semiprotected | semiprotect | semi = This module is subject to page protection.

| File:Ambox warning orange.svg | This Lua module is used on approximately 3,720,000 pages, or roughly 691450% 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 supports Template:If empty. See here for test cases.
