Settings is where users have the ability if given the right permissions to add new teams or users to teams. For example the farm manager can add farm workers via their email address to the main farm team.
The Settings landing page shows user details, user settings and team details. The blue box shown in the top user details section is the API token of the user. This can be used to access the platform data programmatically. Below user details, on the left hand side are user settings and on the right hand side are team settings.
