page: The number of a single page in the source that supports the content. Use either Template:Para or Template:Para, but not both. Displays preceded by p. unless Template:Para. If hyphenated, use Template:Tl to indicate this is intentional (e.g. Template:Para), otherwise several editors and semi-automated tools will assume this was a misuse of the parameter to indicate a page range and will convert Template:Para to Template:Para.
OR: pages: A range of pages in the source that supports the content. Use either Template:Para or Template:Para, but not both. Separate using an en dash (–); separate non-sequential pages with a comma (,); do not use to indicate the total number of pages in the source. Displays preceded by pp. unless Template:Para. Hyphens are automatically converted to en dashes; if hyphens are appropriate because individual page numbers contain hyphens, for example: pp. 3-1–3-15, use double parentheses to tell the template to display the value of Template:Para without processing it, and use Template:Tl to indicate to editors that a hyphen is really intended: Template:Para. Alternatively, use Template:Para, like this: Template:Para.
nopp: Set to y, yes, or true to suppress the p. or pp. notations where this is inappropriate; for example, where Template:Para or Template:Para.
