+## RSS templates
+
+Like with Hookshot, RSS templates must be specified per feed.
+[Upstream documentation](https://github.com/maubot/rss/blob/master/README.md#templates)
+
+Replace X with the feed ID seen in `!rss subscriptions`:
+
+- default: `!rss template X New post in $feed_title: [$title]($link)`
+- Matrix: `!rss template X [$feed_title]($feed_link): [$title]($link) ($date) $summary`
+- IRC: `!rss template X $link $title ($date) $summary ~ $feed_title`
+
+Note: at the time of writing `$author` is not supported?
