@@ -384,11 +422,28 @@ you can implement your own worker class to handle such requests. This allows:
 - Handle and retry network and other errors with queue adapter.
 - ???
 
+Instead of performing request instantly client serializes it, pushes to queue,
+and immediately return control back. The job is then fetched with a worker
+and real API request is performed. And this all is absolutely transparent for the app.
+
 To enable this mode add `async: true` to bot's and botan's config.
 For more information and custom configuration check out
 [docs](http://www.rubydoc.info/github/telegram-bot-rb/telegram-bot/master/Telegram/Bot/Async) or
 [source](https://github.com/telegram-bot-rb/telegram-bot/blob/master/lib/telegram/bot/async.rb).
 
+If you want async mode, but don't want to setup queue, know that Rails 5 are shipped
+with Async adapter by default, and there is
+[Sucker Punch](https://github.com/brandonhilkert/sucker_punch) for Rails 4.
+
+Be aware of some limitations:
+
+- Client will not return API response.
+- Sending files is not available in async mode [now],
+  because them can not be serialized.
+
+To disable async mode for the block of code use `bot.async(false) { bot.send_photo }`.
+Yes, it's threadsafe too.
