+  # ### CI Setup
+  #
+  # With Drone you run the docker images yourself, so you will want to add `bundle exec danger` at the end of
+  # your `.drone.yml`.
+  #
+  #  ``` shell
+  #   build:
+  #     image: golang
+  #       commands:
+  #         - ...
+  #         - bundle exec danger
+  #  ```
+  #
+  # ### Token Setup
+  #
+  # As this is self-hosted, you will need to add the `DANGER_GITHUB_API_TOKEN` to your build user's ENV. The alternative
+  # is to pass in the token as a prefix to the command `DANGER_GITHUB_API_TOKEN="123" bundle exec danger`.
