-Install the ESP8266 Arduino development environment from [esp8266 Arduino](https://github.com/esp8266/Arduino). The software is tested on a Windows PC with Arduino IDE versions 1.6.5r5, 1.6.8 and 1.6.9 and esp8266 Arduino versions 2.1.0 and 2.2.0.

 - I prefer a standalone version of the IDE allowing easy ESP8266 file manipulation. This can be achieved by downloading the Arduino IDE ZIP file for non admin install. After unzipping and before executing ```arduino.exe``` add an empty directory called ```portable```
 - Follow the procedure to install the ESP8266 Arduino development environment

 If you want to be able to upload the OTA file from the IDE to your webserver perform the following changes to the Arduino IDE environment:
 
-- Copy file ```espupload.py``` to directory ```portable\packages\esp8266\hardware\esp8266\2.1.0\tools```
-- Replace files ```boards.txt``` and ```platform.txt``` in directory ```portable\packages\esp8266\hardware\esp8266\2.1.0```

+- Replace files ```boards.txt``` and ```platform.txt``` in directory ```portable\packages\esp8266\hardware\esp8266\2.3.0```
 
 This will provide an additional option ```Tools - Upload Using: OTA_upload```.
