Teams are groups of organization members that you can create to reflect your company or group's structure with cascading access permissions and mentions. Organization members can send notifications to a team or request reviews, and teams can be visible or secret. For more information, see "AUTOTITLE."

You can create independent teams or have multiple levels of nested teams to reflect your group or company's hierarchy. For more information, see "AUTOTITLE."
