 Libraries that don't rely on low-level access to AVR registers should work well. Here are a few libraries that were verified to work:
 
+- [Adafruit_ILI9341](https://github.com/Links2004/Adafruit_ILI9341) - Port of the Adafruit ILI9341 for the ESP8266 
 - [arduinoWebSockets](https://github.com/Links2004/arduinoWebSockets) - WebSocket Server and Client compatible with ESP8266 (RFC6455)
-- [aREST](https://github.com/marcoschwartz/aREST) REST API handler library.
+- [aREST](https://github.com/marcoschwartz/aREST) - REST API handler library.
 - [Blynk](https://github.com/blynkkk/blynk-library) - easy IoT framework for Makers (check out the [Kickstarter page](http://tiny.cc/blynk-kick)).
 - [DallasTemperature](https://github.com/milesburton/Arduino-Temperature-Control-Library.git)
 - [DHT-sensor-library](https://github.com/adafruit/DHT-sensor-library) - Arduino library for the DHT11/DHT22 temperature and humidity sensors. Download latest v1.1.1 library and no changes are necessary.  Older versions should initialize DHT as follows: `DHT dht(DHTPIN, DHTTYPE, 15)`
 - [NeoPixel](https://github.com/adafruit/Adafruit_NeoPixel) - Adafruit's NeoPixel library, now with support for the ESP8266 (use version 1.0.2 or higher from Arduino's library manager).
 - [NeoPixelBus](https://github.com/Makuna/NeoPixelBus) - Arduino NeoPixel library compatible with ESP8266. Use the "NeoPixelAnimator" branch for ESP8266 to get HSL color support and more.
-- [PubSubClient](https://github.com/Imroy/pubsubclient) MQTT library by @Imroy.
+- [PubSubClient](https://github.com/Imroy/pubsubclient) - MQTT library by @Imroy.
 - [RTC](https://github.com/Makuna/Rtc) - Arduino Library for Ds1307 & Ds3231 compatible with ESP8266.
 - [Souliss, Smart Home](https://github.com/souliss/souliss) - Framework for Smart Home based on Arduino, Android and openHAB.
 - [ST7735](https://github.com/nzmichaelh/Adafruit-ST7735-Library) - Adafruit's ST7735 library modified to be compatible with ESP8266.  Just make sure to modify the pins in the examples as they are still AVR specific.
