# Manage Roles and Permissions

[Roles](/docs/concepts/domain-model/roles) in Boundary manage the permissions given to principals ([Users](/docs/concepts/domain-model/users)/[Groups](/docs/concepts/domain-model/groups)). Roles can be defined at the global, org, or project scopes.

In this example, we're going to show you how to create a role in Boundary, assign that roles grants, and assign principals to the role.

~> Note that all resource IDs in this example are illustration only - IDs are uniquely generated for every resource upon creation with the exception being
generated resources in `dev` mode. Please make sure to use the resource IDs that are generated when running this example. For example, if you run
`boundary roles create`, use the resource ID of the role seen in stdout, not the ID in the example command.

# Create a Role

Roles can live in the global, org, or project scopes. In this example we will create a role in the generated org scope in `dev` mode.

# Assign Grants to a Role

Grants describe the actions that the principals should be allowed to perform. For more information on how to format grants see [Permission Grant Formats](https://boundaryproject.io/docs/concepts/security/permissions#permission-grant-formats).
In this example we give a role read and list permissions to all resources.
