About teams
Teams are groups of organization members that share repository access permissions and that you can mention together.
Creating a team
You can create teams to manage repository permissions and mentions for groups of people.
Adding organization members to a team
People with owner or team maintainer permissions can add organization members to teams. People with owner permissions can also add non-members to a team and the organization.
Changing team settings
Team maintainers can edit the name and description of a team, as well as determine whether a team is visible or secret.
Removing organization members from a team
People with owner or team maintainer permissions can remove team members from a team. This may be necessary if a person no longer needs access to a repository the team grants, or if a person is no longer focused on a team's projects.
Deleting a team
Organization owners can delete teams at any time from the team's settings page.
