+# Introduction
+
+This is a bunch of project that aims to provide a reusable platform for different kind of project using ESP8266.
+
+Start by looking at ESP8266 SDK integration in Arduino environment https://github.com/esp8266/Arduino
+
+## WiFiWebServer
+Provide GPIO control by HTTP request
+
+## WiFiAccessPointConfigurator
+Provide GPIO control by HTTP request.
+
+To be able to configure the Wifi credentials without flashing the device, at first boot, the device will create a AP that will help to configure:
+* Wifi SSID to connect to
+* Wifi Passwd to use for SSID
+* A Mdns name to be accessible without IP address (e.g. under Linux : mydevice.local )
+
+Settings can be reconfigured latter by web interface or by pulling down gpio 3
+
+Device can also be put in OTA mode and will wait for OTA from the espota tool.
+
+## WifiControlSensor
+Provide previous WiFiAccessPointConfigurator features and can also measure temperature from a BMP180.
+
+To interface with BMP180, the following library should be installed into Arduino environment: https://github.com/mmaret/BMP180_Breakout_Arduino_Library/archive/master.zip
