The pages in this category are redirects to non-English language terms. If an ISO 639-1, -2 or -3 language already has its own name code and subcategory, then that subcategory should be populated. If there is no usable language code, or if a subcategory does not already exist, then the redirect populates this category. If a language code does exist, then a new subcategory should be created to remove redirects from this category. The |2= parameter in bold below must have an entry in order to populate either this category or one of its subcategories. To add a redirect to this category, place ((Rcat shell|((R from alternative language|1=(the < from > ISO 639 name code)|2=(the < to > ISO 639 name code))))) on the second new line (skip a line) after #REDIRECT [[Target page name]]. For more information follow the links. Never substitute redirect template(s), nor place them on soft redirects.

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 tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme.

This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.

To be clear, this category should only be populated by subcategories and by redirects that are from a language that does not have an ISO 639 language code.
