- Get the latest Raspbian Jessie Lite
- Get Etcher
- Use Etcher to burn the Raspbian image to an sd card, 16GB or higher, probably
- Mount the Raspbian image again and edit
/boot/config.txt
to add
gpu_mem=16
Since the rpi will be headless, there’s no need to give a ton of shared memory to the gpu.
- Boot up the pi, with monitor and keyboard attached. (ssh is not enabled by default)
