(Not sure if you'll already know this yet)

Go down to the bottom were a second list of the categories are listed. You click inside and it will say add categories. You type in the category name you want, and then just enter. To get rid of a catgory go into classic editor and find the categories in the right side of your screen. Click that and you can remove categories.
