## Permission Management
Permission management is normally done by an admin user using the permission management modal:
`IPermissionStore` is the only interface that needs to be implemented to read the value of permissions from a persistence source, generally a database system. Permission management module implements it. See the [permission management module documentation](Modules/Permission-Management.md) for more information
