Workflow

Owner of the Pull Request will be responsible for merge after all requirements are met, including approval from at least one reviewer. Additional changes made after a review will dismiss any approvals and require re-review of the additional updates. Auto merging can be enabled below if additional changes are likely not to be needed. The bot will auto assign reviewers to your Pull Request for you.
