+# smartconfig Example
+
+This example shows how ESP8266 connects to AP with ESPTOUCH. Example does the following steps:
+
+* Download ESPTOUCH APP from app store. [Android source code](https://github.com/EspressifApp/EsptouchForAndroid) and [iOS source code](https://github.com/EspressifApp/EsptouchForIOS) is available.
+
+* Compile this example and upload it to an ESP8266.
+
+* Make sure your phone connect to target AP (2.4GHz).
+
+* Open ESPTOUCH app and input password. There will be success message after few sec.
+
+### Example output
+
+Here is an example of smartconfig console output.

-if you want to use AIRKISS2.0 LAN discovery, should include airkiss.h and include libairkiss.a in makefile.
-
-you can follow the steps below to achieve the function of LAN discovery.  
-1.scan the two-dimension code in your wechat. 
-2.running this smartconfig example.
-3.wait device connect to AP and LAN discovery.
-
-More detailed introduction refer to wechat.
