While effective code review is essential to every successful project, it's not always clear who should review files—even with GitHub's reviewer suggestions. Now repository maintainers can define exactly which people and teams need to review projects using code owners. This new feature automatically requests reviews from the code owners when a pull request changes any owned files.
How code owners work
To specify code owners, create a file named
CODEOWNERS in the repository's root directory (or in
.github/ if you prefer) with the following format:
