Add categories/tags to front matter and they will be displayed on
summary and post pages, with links to taxonomy pages. Example:
+++
date = "2016-09-24T21:28:31+03:00"
title = "Post title"
categories = ["Nature"]
tags = ["Wetland", "Oasis"]
+++
For some reason if you add tags singularly, like:
categories = "Nature"
you get index errors from Hugo. Not sure if I need to parse the
tags differently or just add more logic to test if the terms are
singular or not.
