Hi,
I don’t know how you plan to use this theme. I used it on this website: https://docs.vimeotheque.com/ and it worked great.
The website above is dedicated strictly to documentation. Each post covers a single subject regarding the use of a WP plugin being documented on the website. Posts are grouped under categories.
What I wanted was a simple, straight forward way of displaying a list of posts for each of the categories registered and I wanted to display that on the homepage. So I created a page, used the Knowledbase template on it (from the page settings in WP) and set the page as homepage in WP settings.
Basically, I wanted all categories to be visible on homepage so that a visitor can quickly see all the main topics covered into the documentation.
For example, you want to see how to install the plugin for the first time; you notice the “Getting started” category on homepage and it’s clear: that’s where you should begin.
Hope this makes sense, let me know if you need to ask anything else.
