It is intended to be placed at the end of an article, after the references, external links, navboxes and before any authority control template or categories.

No single parameter is required, however, at least one portal or sister project should be utilized with the use of this template. Since Wikipedia articles typically are in the domain of one or more WikiProjects, and since WikiProjects often have a portal, almost every article should list at least one portal. None of the parameters should be capitalized.

When copying all parameters in either the vertical or horizontal layouts, delete those which are not needed. If no links are needed for a particular type, such as the historical "books", that part of the template will not appear on the page.

Parameter meanings (quick list). Alphabetical order: b: Wikibooks. commons: WikiMedia Commons. d: Wikidata. n: Wikinews. q: Wikiquote. s: Wikisource. species: Wikispecies. v: Wikiversity. voy: Wikivoyage. wikt: Wiktionary.

All parameters, horizontal. Parameters in order they show up in subject bar.

{{Subject bar|commons = y|species = y|voy = y|n = y|wikt = y|b = y|q = y|s = y|v = y|d = y|portal = }}

All parameters, horizontal. In alphabetical order, except for portal which is often removed.

{{Subject bar|b = |commons = |d = |n = |q = |s = |species = |v = |voy = |wikt = |portal = }}

All parameters, vertical. In alphabetical order, except for portal which is often removed.
