 Arduino-compatible IDE with ESP8266 support
 ===========================================
 
+![Linux build status](http://img.shields.io/travis/igrr/Arduino.svg)
+
 This project brings support for ESP8266 chip to the Arduino environment. ESP8266WiFi library bundled with this project has the same interface as the WiFi Shield library, making it easy to re-use existing code and libraries.

+Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux x64.
 
+- Install Arduino 1.6.4 from the [Arduino website](http://www.arduino.cc/en/main/software).
+- Start Arduino and open Perferences window.
+- Enter ```http://arduino.esp8266.com/package_esp8266com_index.json``` into *Additional Board Manager URLs* field. You can add multiple URLs, separating them with commas.
+- Open Boards Manager from Tools > Board menu and install *esp8266* platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
