Welcome to the forums
Hey Dennis,
Right now you will need to manually add the categories to the database. You could always checkout a few open source admin packages such as: https://github.com/FrozenNode/Laravel-Administrator and it should have basic CRUD functionality.
We'll look into a way of integrating adding categories to this package. We are also working on another open source Admin package that it will work seemlessly with. You can follow me on twitter http://twitter.com/tnylea to be notified when it will be released. It's called Voyager, and it's going to be the best laravel admin package out there. Take a look at a few screenshots here: https://dribbble.com/shots/2728557-Voyager-The-Missing-Laravel-Admin
Hope that helps!
And let me know if you have any other questions.
