@@ -75,6 +75,7 @@ Entries are formatted as follows:
 * `destination`: Name of the wiki being redirected to.
 * `destination_base_url`: Fully qualified domain name of the wiki being redirected to.
 * `destination_content_path`: The URL path prefix for article links on the wiki being redirected to. On MediaWiki wikis, it can be found at Special:Version. It is typically `/wiki/` or `/`.
+* `destination_content_prefix`: A prefix that is prepended to article names before performing a search on the destination wiki. This can be useful if a wiki separates its content into different namespaces. For example, if we wanted to redirect a wiki about Super Mario Odyssey to a general Mario wiki that has Odyssey content in a namespace called `Odyssey`, we would set `destination_content_prefix` to `Odyssey`.
 * `destination_platform`: The wiki's software. The current supported options are `mediawiki` and `doku`. If you are contributing a wiki that is on another wiki platform, please open an issue so that support for the platform can be added.
 * `destination_icon`: The name of the wiki's favicon in the [favicons](favicons) folder.
