-defmodule Pleroma.Plugs.RateLimiter do
-  @moduledoc """
-
-  ## Configuration
-
-  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.
-
-  To disable a limiter set its value to `nil`.
-
-  ### Example
-
-      config :pleroma, :rate_limit,
-        one: {1000, 10},
-        two: [{10_000, 10}, {10_000, 50}],
-        foobar: nil
-
-  Here we have three limiters:
-
-  * `one` which is not over 10req/1s
-  * `two` which has two limits: 10req/10s for unauthenticated users and 50req/10s for authenticated users
-  * `foobar` which is disabled
-
-  ## Usage
-
-  AllowedSyntax:
-
-      plug(Pleroma.Plugs.RateLimiter, :limiter_name)
-      plug(Pleroma.Plugs.RateLimiter, {:limiter_name, options})
-
-  Allowed options:
-
-      * `bucket_name` overrides bucket name (e.g. to have a separate limit for a set of actions)
-      * `params` appends values of specified request params (e.g. ["id"]) to bucket name
-
-  Inside a controller:
-
-      plug(Pleroma.Plugs.RateLimiter, :one when action == :one)
-      plug(Pleroma.Plugs.RateLimiter, :two when action in [:two, :three])
-
-      plug(
-        Pleroma.Plugs.RateLimiter,
-        {:status_id_action, bucket_name: "status_id_action:fav_unfav", params: ["id"]}
-        when action in ~w(fav_status unfav_status)a
-      )
-
-  or inside a router pipeline:
-
-      pipeline :api do
-        ...
-        plug(Pleroma.Plugs.RateLimiter, :one)
-        ...
-      end
