+## Via Web Interface 
 
-A Hardware reset can be made (all wifi and services config lost) by pressing and holding GPIO0 hardware button (on the Huzzah WiFi module) for 10s.
+This is the easiest way to update, pre-compiled firmware files `.bin` can be uploaded via the web interface: System > Update. 
 
-Note: Holding the GPIO0 button for 5s will but the WiFi unit into AP (access point) mode to allow the WiFi network to be changed without loosing all the service config
+If for whatever reason the web-interface won't load it's possibel to updated the firmware via CURL:

-## Upload pre-compiled firmware 
+## Via Network OTA
 
-- Download pre-compiled FW from the [OpenEVSE Wifi releases](https://github.com/OpenEVSE/ESP8266_WiFi_v2.x/releases) page
-- Flash using esptool:
+The firmware can also be updated via OTA over a local WiFi network usiong Arduino or Platformio
 
-`esptool.py write_flash 0x000000 firmware.bin`
+`platformio run -t upload --upload-port <IP-ADDRESS>`
 
-Or use esptool GUI (Pyflasher) avilable on windows/mac https://github.com/marcelstoer/nodemcu-pyflasher

-### Compile & Upload Using Arduino IDE
-
-#### 1. Install ESP for Arduino with Boards Manager
-
-From: https://github.com/esp8266/Arduino
-
-Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. ESP Arduino packages are available for Windows, Mac OS, and Linux (32 and 64 bit).
-
-- Install Arduino 1.6.8 from the Arduino website.
-- Start Arduino and open Preferences window.
-- Enter http://arduino.esp8266.com/stable/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).
-
-
-#### 2. Compile and Upload
-
-- Open `src.ino` in the Arduino IDE.
-- Compile and Upload as normal
