 microgear-esp8266-arduino  is a client library that is used to connect an ESP8266 chip to the NETPIE Platform's service for developing IoT applications. For more details on the NETPIE Platform, please visit https://netpie.io .
 
 ## Compatibility
+
 We have tested this library and found it compatible with (but not limited to) the following hardware
 - ESP8266-01, 07, 12E, 12F
 - NodeMCU v1, v2, V3
 - Espresso Lite v2.0
 
+## Outgoing Network Port
+
+Make sure ther following ports are allowed to connect from your network.
+- Non-TLS mode : 8080 and 1883 (the library uses this mode by default)
+- TLS mode : 8081 and 8883 (still under testing)
+
 ## Installation
 *  Download Arduino IDE 1.6.9 or later from https://www.arduino.cc/en/Main/Software
 *  After installation, open Preferences

 In the case that the microgear want to send a message to an unspecified receiver, the developer can use the function publish to the desired topic, which all the microgears that subscribe such topic will receive a message.
 
 **arguments**
 * *topic* - name of topic to be send a message to.
 * *message* - message to be sent.
+* *decimal* - number of digits after the deimal point.
 * *retained* - retain a message or not, the default is false (optional))
