 ** To learn more about running the PipelineRun, see the link:https://pipelinesascode.com/docs/guide/running/#running-the-pipelinerun[Running the PipelineRun guide] from Pipelines as Code docs. 
 * Consider changing the PipelineRun definition source by setting the `pipelinerun_provenance` setting to `default_branch`. With this setting, Pipelines as Code uses the PipelineRun definition from the default branch of the repository, usually `main` or `master`, and only contributors with default branch merge rights can modify the PipelineRun.

-If you don’t set `pipelinerun_provenance`, you allow the default behavior: the PipelineRun definition is fetched from the branch where the PipelineRun event is triggered, and link:https://pipelinesascode.com/docs/guide/running/[submitters who are allowed to run a PipelineRun] can get access to the PipelineRun definition.  External submitters cannot run a PipelineRun and need a repository owner to comment `/ok-to-test` on a PR. In these cases `pipelinerun_provenance: default_branch` still applies, and the PipelineRun definition is taken from the default branch.

 Testing changes to the PipelineRun is easier with the default behavior because PipelineRun changes are tested when a user submits a pull request, before the merge.

-Setting the `pipelinerun_provenance` setting to `default_branch` is more cautious because PipelineRun changes are tested only after a repository owner reviews and merges them. We recommend that repository owners review all changes to PipelineRun very carefully before the merge. If the proposed change doesn't work correctly, a repository owner might need to merge a few changes to debug the PipelineRun.
