The broad steps to do this are:
* Download the Raspbian image (the 'Lite' version, with no desktop, is perfect)
* Unzip this download, and create an SD card from this image file. E.g. using [<googa>https://sourceforge.net/projects/win32diskimager/ |Win32 Disk Imager]</googa>* On that SD card, edit the /etc/network/interfaces file to enable Wifi (or an Ethernet connection). The first step in [<googa>http://trendblog.net/raspberry-pi-basic-headless-setup-without-cables/ |this guide] </googa> explains how to do this. (Don't worry about the other steps for now)
* Once Raspbian is installed, you will be needing to SSH onto the Pi, to then install Box Of Stops. However, with recent versions of Raspbian SSH has been locked down. The simplest way to re-enable SSH for a headless (no monitor) install is to create a /ssh file. This is just a 'marker file' to instruct Raspbian to start SSH when it boots, and can be an empty file. See Step 3 [https://hackernoon.com/raspberry-pi-headless-install-462ccabd75d0 here] for more detail on how to do this
* Now boot your Pi with this SD card. This first installation will take a few minutes, though after this the boot sequence is much quicker
* Then SSH onto the Pi, e.g. using [<googa>http://www.putty.org/ |PuTTY]</googa>. If you are unsure of the IP address of the Pi, the best option is to use the management screen of your Wifi router - this should list the attached devices
* Once you have an SSH session, you are up and running with a command prompt and ready to [http://boxofstops.com/install install Box Of Stops] as normal
