Create a Team from the button on the top right corner.
Choose a unique name that all users can utilize. Select Add.
The planner/user that created the Team will automatically become the Leader.
Add Team Members as required, but it is advised to add an Approver and an Installer; at the least.
The options for user Project Roles is either Leader, Member or a Viewer.
A Leader can edit details on the project, a Member can add and delete tasks, and a Viewer is read only.
The Project can now be created, and the team is ready to start designing the plan.
Team members can be added at any time, and their roles modified.
