 ## Overview
+A few months ago, I came across a project called Wifinfo. It's a small board, based on an ESP8266, which retrieves information from the French power meters and displays them, or sends them across the network. The PCB was cheap, and I though I could use one, so I built some boards ! Turns out, I can't use them: the telemetry option is disabled in my power meter...
 ## Hardware
+### PCB
+I uploaded the files on OSHPark and also shared them, so anyone can easily order them: [OSH Park](https://oshpark.com/shared_projects/Rjzd7tY7)

+### Tools
+You need:
+- A decent (250mA) 5v PSU, like a phone charger, or a battery.
+- An USB-Serial adapter, which can easily be sourced from eBay.
 ## Software
 ### Tools
+The firmware is an Arduino sketch, so you will need:
+- The Arduino IDE. I used v1.6.7, from [the Arduino website](https://www.arduino.cc/en/Main/Software)
+- The ESP8266 _extension_ for the Arduino IDE, from [Github](https://github.com/esp8266/Arduino)
+- The "ESP8266 Sketch data upload" tool for the Arduino IDE, from [Github](https://github.com/esp8266/arduino-esp8266fs-plugin/releases/)
+- Some libraries such as:
+  - NeoPixelBus, for ESP8266. Make sure to fetch a working branch, from [Github](https://github.com/Makuna/NeoPixelBus).
+    I took a "random" one, and it compiles fine, but the LED doesn't work properly...
+  -
 ### Firmware
+Grab the firmware from the LibTeleinfo Github project, in the `examples/Wifinfo`folder.
+There's currently a bug in the index.html file: the [issue](https://github.com/hallard/LibTeleinfo/issues/3) with a _fix_, on Github.
 ### Upload
+#### Wiring and process
+You need to put a jumper on the board between the __TX__ and __TX1__ pins, on the three pin header on the right.
+Connect your serial Adapter to the board (on the six pins header on the right): RX on TX, TX on RX, GND on GND.
+I used an external power supply but you can also probably use the 5v pin to power the board.
+To put the ESP8266 in _Flash mode_, press the Flash switch, hold it, press the Reset switch, relase Reset, release Flash. Should be ok.
+Select the __good__ board type and options (the default ones are usually okay).
+#### Upload the data
+* Load the Wifinfo sketch
+* Put the ESP266 in _Flash mode_
+* Tools > ESP8266 Sketch Data upload
+#### Upload the firmware
+* Load the Wifinfo sketch
+* Put the ESP266 in _Flash mode_
+* Upload sketch
