+1. `Multiple WiFi Credentials (SSID, Password) and system will autoconnect to the best and available WiFi SSID.`
+2. `Multiple Blynk Credentials (Server, Token) and system will autoconnect to the available Blynk Servers.`

-This `Blynk.begin()` is not a blocking call, so you can use it for critical functions requiring in loop(). 
+You can see that the system automatically detect and connect to the best or avaiable WiFi APs and/or Blynk Servers, whenever interruption happens. This feature is very useful for systems requiring high degree of reliability.
+
+Moreover, this `Blynk.begin()` is not a blocking call, so you can use it for critical functions requiring in loop(). 
 Anyway, this is better for projects using Blynk just for GUI (graphical user interface).
 
 In operation, if WiFi or Blynk connection is lost, `Blynk.run()` will try reconnecting automatically. Therefore, `Blynk.run()` must be called in the `loop()` function. Don't use:
