+Overwrite the individual rate limit for a specific route
+
+From time to time it can be necessary to extend the rate limit of a specific route,
+depending on your usage pattern or when you script some actions.
+Instead of completely disabling the rate limit or excluding an IP address from the
+rate limit, the following config allows to overwrite the rate limit duration and period.
+
+The first level key is the name of the route. You can find the route name from a URL
+using the ``occ router:list`` command of your server.
+
+You can also specify different limits for logged-in users with the ``user`` key
+and not-logged-in users with the ``anon`` key. However, if there is no specific ``user`` limit,
+the ``anon`` limit is also applied for logged-in users.
+
+Defaults to empty array ``[]``
