Ghost has a single, powerful organisational taxonomy, called tags.
It doesn't matter whether you want to call them categories, tags, boxes, or
anything else. You can think of Ghost tags a lot like Gmail labels. By tagging
posts with one or more keyword, you can organise articles into buckets of
related content.
Basic tagging
When you write a post, you can assign tags to help differentiate between
categories of content. For example, you might tag some posts with News and other
posts with Cyclin
