In case @maestromac's answer is not clear enough, the top of your post would look like this at the beginning:
---
title: ""
published: false
description: ""
tags:
---
And to add the cover_image
, you will have to do it manually:
---
title:
published: false
description:
tags:
cover_image: <IMAGE-URL>
---
And that image URL should be ending on a image file extension like .jpg
or .png
.
By adding
cover_image
into the front matter. Click on "Help" to the left of "Markdown" on top when you are writing a post for more info.
