テンプレート:Historical information needed/doc

Usage

{{Historical information needed}} will suffice.
{{Historical information needed|date=5月 2025}} using current month and year. N.B. Adding a date does not affect how the article is categorized. (There are no date-specific categories for articles lacking historical information.)
{{Historical information needed|Specifics|date=5月 2025}} where Specifics is a brief sentence describing missing historical information. For example:
{{Historical information needed|When and where was this invented? Who contributed to its development? How did it change over time?|date=5月 2025}}
