 You can use {pac} resolver annotations to reference `Task` and `Pipeline` custom resource (CR) definitions. The {pac} resolver fetches the definitions from the locations that you specify in the annotations. If there is any error while fetching the remote tasks or parsing them, {pac} stops processing the tasks.
 
 If you reference a remote task in a pipeline run, or a pipeline in a `PipelineRun` or a `PipelineSpec` object, the {pac} resolver automatically resolves the referenced resource and includes it in the resulting `PipelineRun` custom resource (CR).
