Creating a commit on behalf of an organization

Developers can indicate their intent to contribute to a project on behalf of an organization. This can help minimize confusion over ownership, for example, when contributing to a third-party project on behalf of your employer. For a given commit to be associated with an organization:

  1. The committer must add an On-behalf-of commit trailer to the commit, in the form of: On-behalf-of: @ORG <ORG CONTACT EMAIL>,
  2. The committer must be a member of the organization,
  3. The commit must be committed with an email in the organization’s verified domain, and
  4. The commit must be signed.

Support for the On-behalf-of commit trailer is currently in public beta. For more information, see creating a commit on behalf of an organization.
