+ * and keeps track of its transmission and converts its reponses back to [`ResponseInterface`](#responseinterface) objects.
+ *
+ * It also registers everything with the main [`EventLoop`](https://github.com/reactphp/event-loop#usage)
+ * and the default [`Connector`](https://github.com/reactphp/socket-client) and [DNS `Resolver`](https://github.com/reactphp/dns).
+ *
+ * The `Sender` class mostly exists in order to abstract changes on the underlying
+ * components away from this package in order to provide backwards and forwards
+ * compatibility.
+ *
+ * @internal You SHOULD NOT rely on this API, it is subject to change without prior notice!
