-# ESP8266-01-AWS-MQTT
-
-Arduino examples of connecting ESP8266 to AWS IOT Core
-
-## Instructions
+# Connects and Arduino board to WiFi using an ESP8266 ESP01 module, then sends data to AWS IOT through an MQTT topic
 
 ## Software requirements
 
 ESP8266
 - Use ESP8266 Arduino Core version **2.5.0-beta2 or greater**
 - Will **NOT** work on ESP8266 Arduino Core v2.4.2 !!!
 
-### Libraries Needed
+This repo accompanies the "Connected Weather Station" [project](https://github.com/MecaHumArduino/arduino-uno-aws-weather-station) but can also be used as a standalone repo to learn how an [Arduino Uno](https://amzn.to/2RnHhPY) board can communicate with an ESP8266 WiFi module in order to gain access to the internet.

+ESP8266 ESP01 - Schematic Diagram
+------------------------------
+
+The ESP8266 WiFi Module is a self-contained stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. The ESP8266 module is an extremely cost-effective board with a huge, and ever-growing, community.
