# Teams, Users & Permissions

As an [admin](https://docs.forestadmin.com/user-guide/project-settings/manage-roles#permission-level), you can use [Roles](https://docs.forestadmin.com/user-guide/project-settings/teams-and-users/manage-roles), [Teams](https://docs.forestadmin.com/user-guide/project-settings/teams-and-users/create-and-manage-a-team) and [Scopes](https://docs.forestadmin.com/user-guide/collections/scopes) to control which users have access to specific resources. See [add and manage users](https://docs.forestadmin.com/user-guide/project-settings/teams-and-users/add-and-manage-users) to learn how to invite users to Forest Admin.

Forest Admin's user permissions can be summarised by the following features:

1. [**Teams**](https://docs.forestadmin.com/user-guide/project-settings/teams-and-users/create-and-manage-a-team)**:** You can have as many teams as necessary. Each user can belong to 1 or more team(s). Each user has 1 role which applies to all the teams he belongs to.
2. [**Team layout**](https://docs.forestadmin.com/user-guide/project-settings/create-and-manage-a-team#manage-your-teams-layout)**:** The layout of a team is the way every visible aspect of your UI is set, from columns to Smart Views to widgets.
3. [**Roles**](https://docs.forestadmin.com/user-guide/project-settings/teams-and-users/manage-roles)**:** Roles allow you to manage all Smart Actions permissions, Collection permissions and access to Environments applied to a group of users. Each user has 1 role which applies to all the teams he belongs to.
4. [**Permission levels**](https://docs.forestadmin.com/user-guide/project-settings/manage-roles#permission-level)**:** The permission level of a user determines what Forest Admin administration permissions he has (e.g. Admin, Developer, Editor, User).
5. [**Scopes**](https://docs.forestadmin.com/user-guide/collections/scopes)**:** a scope is a pre-defined filter which applies to a collection and all its segments. It can be applied to specific teams.
