PermissionsBukkit {Plugin}

I need some help with permissions I'm new at this.


Code:
users:
ConspiracyWizard:
permissions:
permissions.example: true
groups:
- admin
groups:
default:
permissions:
permissions.build: false
admin:
permissions:
permissions.*: true
inheritance:
- user
user:
permissions:
permissions.build: true
worlds:
creative:
coolplugin.item: true
inheritance:
- default
messages:
build: '&cYou do not have permission to build here.'


I would like in the permissions:
Admin
Mod
Super Admin
Builder
AdvBuilder
Engineer

and some more if you want.
