+The options for the Conditional stage are:
+
+### `condition`
+The condition that each RSS item must match for the other pipeline stage to be applied. This can either be a full Filter object or a single Rule object, both of which are described [here](https://git.shadowfacts.net/shadowfacts/frenzy/wiki/Filtering).
+
+### `stage`
+A string containing the module name of the pipeline stage that should be applied if the `condition` matches an RSS item.
+
+### `opts`
+An object containing the options to provide to the other pipeline stage.
