+
+  To enable the cache add the plug to a router pipeline or controller:
+
+      plug(Pleroma.Plugs.Cache)
+
+  ## Configuration
+
+  To configure the plug you need to pass settings as the second argument to the `plug/2` macro:
+
+      plug(Pleroma.Plugs.Cache, [ttl: nil, query_params: true])
+
+  Available options:
+
+  - `ttl`:  An expiration time (time-to-live). This value should be in milliseconds or `nil` to disable expiration. Defaults to `nil`.
+  - `query_params`: Take URL query string into account (`true`), ignore it (`false`) or limit to specific params only (list). Defaults to `true`.
+
+  Additionally, you can overwrite the TTL inside a controller action by assigning `cache_ttl` to the connection struct:
+
+      def index(conn, _params) do
+        ttl = 60_000 # one minute
