+This repo is setup in a way that if you enable a personal drone server to build your fork it will
+ build and publish your image (makes it easier to test PRs and use the image till the contributions get merged)

+* on your server (or cloud.drone.io) just make sure you have DOCKER_USERNAME, DOCKER_PASSWORD, and PLUGIN_REPO set as secrets
