## How to use it

1. Make sure that your project has 

      [`package.json`](https://docs.npmjs.com/cli/v6/configuring-npm/package-json){:target="_blank"}

1. If you don't already have a lint package installed in your project, you must specified the `NG_LINT_PACKAGE` variable.

1. Add this job URL inside the `include` list of your `.gitlab-ci.yml` file (see the [quick setup](/use-the-hub/#quick-setup)). You can specify [a fixed version](#changelog) instead of `latest`.

    ```yaml

      - remote: 'https://jobs.r2devops.io/latest/ng_lint.yml'
