The Screenbot integration requires the Screenbot Client to be running on your machine. Click the button below to download it (Screenbot currently requires OS X 10.10 and up):
Once you've downloaded Screenbot, drag it to your Applications folder and launch it. Screenbot will then guide you through signing in through your Slack account.
