'feed name' => [
	'page' => <message name>,
	'title' => <message name>,
	'description' => <message name>,
	'entryName' => <message name>,
]

Mandatory items:

'page'

Name of the interface message that contains an expression that evaluates to the title of the page with today's feed entry. For example, for English Wikipedia's featured articles feed it could contain Wikipedia:Today's featured article/{{#time:F j, Y}} that evaluates (using ParserFunctions, but ordinary date/time magic words may be used as well) to Wikipedia:Today's featured article/June 17, 2025. This message always uses content language.

'title'

Name of the interface message that contains feed title, for example "My Page of the Day Feed".

'description'

A longer description of the feed, used for ‎<subtitle> Atom element, and ‎<description> RSS element.

'entryName'

Name of the interface message that contains heading of feed's individual entries.

Also see below for optional settings.

Default value:

[
	'limit' => 10,
	'inUserLanguage' => false,
]

'limit'

Maximum number of entries (ie number of days) in the feed.

'inUserLanguage'

Whether user's preferred language should be honored by the feed. For example, it doesn't make much sense to have English Wikipedia's featured articles feed in languages other than English as the content is always in English anyway. But Commons' picture of the day feed contains images and their descriptions that are available in many languages, so it actually benefits from its description's localisation.
