+
+## Resources
+
+You'll need a rasbpiOs image, and the kernel and dtb for qemu 
+
+## Procedure
+
+### Enlarge img
+
+The downloaded img is resized on the SD card during the installation. We will need more space on the img. Qemu has command for that :
+
+```
+qemu-img resize rpi.img +1G
+```
+
+Install dependencies :
+
+```
+apt install git sqlite3 python3-pip python3-click python3-requests python3-netifaces python3-serial
+```
+
+Deploy pyHeatpump. Replace MONITORING_SERVER with the address of your server :
+```
+mkdir /var/lib/pyheatpump
+echo 'pip3 install --upgrade git+https://git.yannweb.net/maxime-alves/pyHeatpump.git' > /var/lib/pyheatpump/pyheatpump_upgrade.sh
