 ## Jobs
 
-### `docker-lint` job
-
-This job performs a [Lint](https://github.com/projectatomic/dockerfile_lint) on your `Dockerfile`.
-
-It is bound to the `build` stage, and uses the following variables:
-
-| Name                  | Description                            | Default value                           |
-| --------------------- | -------------------------------------- | --------------------------------------- |
-| `DOCKER_LINT_ENABLED` | Set to `true` to enable dockerlint | _(none: disabled by default)_ |
-| `DOCKER_LINT_IMAGE`   | The dockerlint image                   | `registry.hub.docker.com/projectatomic/dockerfile-lint:latest`  |
-| `DOCKER_LINT_ARGS`    | Additional `dockerfile_lint` arguments | _(none)_                                |
-
-In case you have to disable some rules, copy and edit the [rules](https://github.com/projectatomic/dockerfile_lint#extending-and-customizing-rule-files) into `mycustomdockerlint.yml` and set `DOCKER_LINT_ARGS: '-r mycustomdockerlint.yml'`
