 ### Contribution
 
-TBD
+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)
+
+* Build local ```DRONE_REPO_OWNER=josmo DRONE_REPO_NAME=drone-helm drone exec```
+* on your server just make sure you have DOCKER_USERNAME, DOCKER_PASSWORD, and PLUGIN_REPO set as secrets
