v1.0.1
The img.gz release is an SD-card image for raspberry pi all versions. It requires a 2GB SD-card to fit, since it has one 500MB partition and one 1GB partition defined (although the total amount occupied is approx 130MB).
Write to the SD-card using Win32DiskImager for Windows, or the dd command for Linux and macOS. You may find instructions for this here: http://elinux.org/RPi_Easy_SD_Card_Setup
