+  Telecommande QO100
+===========================
+
+## Pre-requis 
+
+<code>sudo apt-get install rpi.gpio git</code>
+
+<br>ou en manuel
+
+<code>wget https://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.5.11.tar.gz</code><br>
+<code>tar -xvf RPi.GPIO-0.5.11.tar.gz</code><br>
+<code>cd RPi.GPIO-0.5.11</code><br>
+<code>sudo python setup.py install</code><br>
+
+## 1) Installation 
+Commande de 16 relais<br>
+Pour installer ce script, aller dans /home/pi<br>
+
+copier control.zip et déziper le dans /home/pi<br>
+<br>
+
+## 2) Pour un démarrage auto 
+
+éditer dans /etc/rc.local<br>
+<code>sudo nano /etc/rc.local</code><br>
+ajouter en fin avant exit<br>
+
+#gestion Relay a 0<br>
+<code>./home/pi/relay.py power 1</code><br>
+<code>gohttp.sh</code><br>
+
+puis de faire un fichier executable<br>
+gohttp.sh dans /usr/local/sbin contenant:<br>
+```
+#!/bin/bash
+cd /home/pi
+./gohttp.py
+exit 0
+```
+
+faire un reboot<br>
+
+configurer config.json<br>
+
+url= ip du RPi<br>
+port= le port choisi<br>
+com1 à 16 = les discription des relais<br>
+
+## 3) Pour le arduino nano
+
+programmer le avec telemetry.ino<br>
+cabler USB sur le port com du raspberry pi<br>
+Dans schema vous avec le plan et les fichier gerber<br>
