+## :rate_limit
+
+This is an advanced feature and disabled by default.
+
+A keyword list of rate limiters where a key is a limiter name and value is the limiter configuration. The basic configuration is a tuple where:
+
+* The first element: `scale` (Integer). The time scale in milliseconds.
+* The second element: `limit` (Integer). How many requests to limit in the time scale provided.
+
+It is also possible to have different limits for unauthenticated and authenticated users: the keyword value must be a list of two tuples where the first one is a config for unauthenticated users and the second one is for authenticated.
+
+See [`Pleroma.Plugs.RateLimiter`](Pleroma.Plugs.RateLimiter.html) documentation for examples.
+
+Supported rate limiters:
+
+* `:search` for the search requests (account & status search etc.)
+* `:app_account_creation` for registering user accounts from the same IP address
+* `:relations_actions` for actions on relations with all users (follow, unfollow)
+* `:relation_id_action` for actions on relation with a specific user (follow, unfollow)
+* `:statuses_actions` for create / delete / fav / unfav / reblog / unreblog actions on any statuses
+* `:status_id_action` for fav / unfav or reblog / unreblog actions on the same status by the same user
+
+## :web_cache_ttl
