How to use the grassbian image

You can get the latest image here

Grab a tool like etcher or any tool that burns images to SD cards
Burn the image
Eject and re-insert the card, go into the mounted drive partition (boot partition for Linux afficionados)
Copy the certs/ and config/ folders from the .tar.gz you recieved when you created a greengrass core into the boot partition in the greengrass folder
(optional) Add a file titled ssh with no extension if you want to ssh into your raspberry pi
(optional) Set up WiFi headlessly
Eject sd and place it into raspberry pi and apply power to pi
If you haven't set wifi up on the SD card, do so now with an attached keybeard and mouse. Otherwise, you can ssh in if you completed the ssh and headless wifi step.
On the Pi, after boot, run sudo systemctl status greengrass.service to ensure greengrass service has booted and is running
If not, sudo systemctl stop greengrass.service and cd /greengrass/ggc/core/, then ./greengrassd to see output from startup sequences for troubleshooting
