 This installation of Home Assistant requires the Raspberry Pi to run [Raspbian Lite](https://www.raspberrypi.org/downloads/raspbian/). The installation will be installed in a [Virtual Environment](/docs/installation/virtualenv) with minimal overhead. Instructions assume this is a new installation of Raspbian Lite.
 
+You must have Python 3.5.3 or later installed, which is the case for Raspbian Stretch.

 Although these installation steps specifically mention a Raspberry Pi, you can go ahead and proceed on any Linux install as well.  This guide is also referred to as the "Advanced Guide" for a virtual environment install.
