You can invite users to become collaborators to your personal repository.

Repositories owned by an organization can grant more granular access. For more information, see "Access permissions on GitHub."

Note: GitHub limits the number of people who can be added to a repository within a 24-hour period. If you exceed this limit, either wait 24 hours or create an organization.

  1. Ask for the username of the person you're inviting as a collaborator. If they don't have a username yet, they can sign up for GitHub.
  2. On GitHub, navigate to the main page of the repository.

  3. Under your repository name, click Settings. Repository settings button

  4. In the left sidebar, click Collaborators. Repository settings sidebar with Collaborators highlighted

  5. Under "Collaborators", start typing the collaborator's username.
  6. Select the collaborator's username from the drop-down menu. Collaborator list drop-down menu
  7. Click Add collaborator. Add button

  8. The user will receive an email inviting them to the repository. Once they accept your invitation, they will have collaborator access to your repository.
