+Home Assistant requires the Raspberry Pi to run [Raspbian Jessie](https://www.raspberrypi.org/downloads/raspbian/). This version was released on September 24, 2015 and comes by default with Python 3.4 which is required for Home Assistant.
+
+Execute the following code in a console:
+
+```bash
+$ sudo pip3 install homeassistant
+$ hass
+```
+
+Running these commands will:
+
+ - Install Home Assistant
+ - Launch Home Assistant and serve the web interface on [http://localhost:8123](http://localhost:8123)
+
+There is also a [video tutorial](https://www.youtube.com/watch?v=GjzOXkPb7XE) created by [brusc](https://github.com/brusc).
+
