Workflow quality features like statuses, pre-receive hooks, protected branches, and required status checks help collaborators make contributions that meet conditions set by organization and repository administrators.

About status checks

Status checks let you know if your commits meet the conditions set for the repository you're contributing to.

Working with protected branches

If you're working on a protected branch, you won't be able to make irrevocable changes to the branch. Repository administrators may also enable required status checks, required pull request reviews, or required commit signing on the protected branch, which will add additional requirements to the mergeability of your work on the protected branch.

Working with pre-receive hooks

Pre-receive hooks enforce rules for contributions before commits may be pushed to a repository.
