  | pre-alpha | prealpha | pa | experimental = This module is rated as pre-alpha. It is incomplete and may or may not be in active development. Do not use it in article namespace pages. A module remains in pre-alpha until its developer, or another editor who adopts it if it is abandoned for some time, considers the basic structure complete.
  | alpha | a                 = This module  is rated as alpha. It is ready for limited use and third-party feedback. It may be used on a small number of pages, but should be monitored closely. Suggestions for new features or adjustments to input and output are welcome.
  | beta | b                  = This module  is rated as beta. It is considered ready for widespread use, but as it is still relatively new, it should be applied with some caution to ensure results are as expected.
  | release | r | general | g | stable | protected | protect | p | semiprotected | semiprotect | semi = This module  is rated as ready for general use. It has reached a mature state, is considered relatively stable and bug-free, and may be used wherever appropriate. It can be mentioned on help pages and other Wikipedia resources as an option for new users. To minimise server load and avoid disruptive output, improvements should be developed through sandbox testing rather than repeated trial-and-error editing.
  | broken | br | unstable    = This module  is rated as unstable. It has missing dependencies, compatibility issues, or output errors that make it unusable. Editors are encouraged to improve its compatibility or nominate it for deletion if it cannot be fixed.
  | deprecated | d | defunct  = This module  is rated as deprecated and defunct.{{#if:|{{#iferror:{{#expr:1}}
