+In order to begin using the workflow-restarter, you need to first raise a PR and add the workflow restarter to your target repository.  In other words, for the `workflow-restarter` to work, it must be merged into the `main` branch before it can be referenced by other workflows (this seems to be a github action feature).
 
 * Copy [workflow-restarter.yml](./workflow-restarter/workflow-restarter.yml) and [workflow-restarter-test.yml](./workflow-restarter/workflow-restarter-test.yml) to the `.github/workflows` directory of your target directory.
 * Raise and merge a PR adding the above to the main branch of your repository.
 * Verify that the `Workflow Restarter TEST` workflow works as expected.  See the [Appendix](#verify-workflow-restarter-with-workflow-restarter-test) for more information on what you should expect to see.
 
-Once the above `Workflow Restarter TEST` is working then you should be able to add the workflow restarter to any of your existing github workflows.  The key is to re-use the `on-failure-workflow-restarter-proxy` located in the `Workflow Restarter TEST`.  For example, the following will trigger a restart if either the `acceptance` or the `unit` jobs preceeding it fail.  A restart of the failing jobs will be attempted 3 times at which point if the failing jobs continue to fail, then the workflow will be marked as failed.  If, however, at any point the `acceptance` and `unit` both pass fine then the restarted workflow will be marked as successful
