 However, Dokku currently only supports the nodes `scripts.dokku.predeploy` and `scripts.dokku.postdeploy`.
 For buildpack apps, simply place an `app.json` file in the root of your repository.
 For dockerfile apps, place `app.json` in the configured `WORKDIR` directory; otherwise Dokku defaults to the buildpack app behavior of looking in `/app`.

+- Example:
