mudra.update_roles(params, function(callback) {
   console.log(response);
});

mudra.create_permission(params, function(response) {
   console.log(response);
});

####Update Permission (add or remove roles)

var params = {username: '[e-mail]', hash: '$2a$08$4Y7NNgKwZavoT8B.xy6RyuZPXOpxsitDNjq9nSlApRFh/ZAVL3WV2', permission: 'cancel_order'};
mudra.check_permission(params, function(callback) {
   console.log(response);
});

###Contexts For example, a project might require readonly privileges given to a certain group but edit privileges given to another group. Admins might get all privileges. You can add permissions by using contexts as follows

var params = {
                "permission": "important_project",
                "roles": [
                    "admin"
                ],
                "context": [
                    {
                        "read": [
                            "read_group",
                            "edit_group"
                        ],
                        "edit": [
                            "edit_group"
                        ]
                    }
                ]
            };

mudra.update_permission(params, function(callback) {
   console.log(response);
});
