# Assigning Specialties
Assigning staff specialties and service categories is crucial when setting up SimpleSpa. Staff members become bookable online for a service only if they have the corresponding service category assigned
In the [Staff](https://my.simplespa.com/staff.php) page, you can easily assign the staff specialties per category by pressing the magic wand button  from the popup you can add or remove service categories that the staff provides. Adding service categories/specialties will change availability for the staff/provider online. Staff that has assigned a category will be bookable also online for the services within that service category. Staff that is not assigned with a category will not be bookable online for services in that category.
