Categories are "types" of things that are being tagged/tracked. This might be a specific type of equipment or a type of worker. Tags can only belong to one category. For example: "XRay Machines" or "Infusion Pumps" might be appropriate categories.
1) Select the Categories menu from the lefthand menu of the admin portal.
2) Select "Add"
3) Enter the category Name. This can be edited or changed later.
Categories must be created before a Tag can be added.
