-### `Req.Response.Async`
+### `%Req.Response.Async{}`
 
 In previous releases we added ability to stream response body chunks into the current process
 mailbox using the `into: :self` option. When such is used, the `response.body` is now set to
 [`Req.Response.Async`] struct which implements the [`Enumerable`] protocol.
 
+Here's a quick example:

 ```elixir
-iex> resp = Req.get!("http://httpbin.org/stream/2", into: :self)
-iex> resp.body
-#Req.Response.Async<...>

-`Req.Response.Async` is an experimental feature which may change before or after Req v1.0.
+Here is another example where we use Req to talk to two different servers. The first server
+produces some test data, strings `"foo"`, `"bar"` and `"baz"`. The second one is an "echo" server, it simply
+responds with the request body it returned. We then stream data from one server, transform it, and
+stream it to the other one:
+
+```elixir
+Mix.install([
+  {:req, "~> 0.5"},
+  {:bandit, "~> 1.0"}
+])
+
+{:ok, _} =
+  Bandit.start_link(
+    scheme: :http,
+    port: 4000,
+    plug: fn conn, _ ->
+      conn = Plug.Conn.send_chunked(conn, 200)
+      {:ok, conn} = Plug.Conn.chunk(conn, "foo")
+      {:ok, conn} = Plug.Conn.chunk(conn, "bar")
+      {:ok, conn} = Plug.Conn.chunk(conn, "baz")
+      conn
+    end
+  )

+  Bandit.start_link(

+      Plug.Conn.send_resp(conn, 200, body)
