Using for arduino

We are working on a project that needs to connect arduino to android app, so for that we planned to use services. The arduino we have is arduino nano ATmega328, in addition to a WiFi component (ESP8266).

The problem is that supplied a parse library for two specific wifi module arduinos: Yun and Zero, while the one we have is Nano which is not suitable for it.

So our question is: Did any one connected a Nano arduino to using ESP8266 module? Or if not can you give us a simple way on how to connect the android app to the Nano arduino?
