-You will need to install Home Assistant before we can get started. You can install Home Assistant on your computer, or you can turn a Raspberry Pi into a dedicated Home Assistant hub.
+First you will need to install Home Assistant before we can get started:
 
+We have developed **Hass.io** to turn your device into a dedicated Home Assistant hub controlled by a nice webinterface.
+For Raspberry Pi and Intel NUC we offer configured images. Flash the image, setup WiFi (if required) and everything else can be done inside the Hass.io webinterface. Great, isn't it?
+
+Also Home Assistant runs on any other device that supports **Python 3**.
