Download Raspbian - wget https://downloads.raspberrypi.org/raspbian_lite_latest
Unmount the SD card - diskutil unmountDisk /dev/disk4 or whatever your disk path is
Mount the Raspbian image to the card - sudo dd if=PATH-TO-RASPBIAN-IMAGE of=/dev/disk4` or whatever your disk path is
Enable SSH on the Pi - cd /volumes && ls. You should see a boot partition from the SD card cd boot && touch ssh
Setup WiFi on the PI - While still in the boot partition of the card type nano wpa_supplicant.conf and enter network={ ssid="YOUR-SSID" psk="YOUR-WIFI-PASSWORD" }
Boot the PI - Unmount the card diskutil unmountDisk /dev/disk4 (or whatever your disk path is) and put it in the

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

	"selector": "source.python"
	}

	Then save it with a meaningful name like: python3.sublime-build
