This category contains pages to which a large, significant change is being made, and are thus best left alone until this change is done, to avoid edit conflicts or inadvertent reversion of changes. As Wikipedia articles should be open to editing by anyone, pages should only be tagged in this way for a short time.

This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set.

See also Category:Pages actively undergoing construction and the accompanying {{underconstruction}} template, used when making a series of significant changes over a longer period of time. Remove this template from an article if it has been tagged for some time with no sign of any changes.

Following templates add pages to this category:

• {{in use}}
• {{in creation}}
• {{DYK in use}}
