This extension lets you draw and share your drawings on Slack. Check the video and screenshot to see how to use it.
Go to the options page of the extension and put your Slack token, which you can get from https://api.slack.com/custom-integrations/legacy-tokens (click you on the green button "Create token" and you'll get a token like xoxp-0123456789-12345678).
