 1. Create and/or customize Hardware, Template, and Workflow objects and apply them to the cluster. You can use the Hardware, Template, and Workflow in this repo, in the `vagrant/` directory, as a base from which to start.
 
    ```bash
-   kubectl apply -f my-hardware.yaml
-   kubectl apply -f my-template.yaml
-   kubectl apply -f my-workflow.yaml
