### ERROR: You must define "cards" front-matter YAML
{: style="color:red" }
This template requires that you insert YAML at the top of your document
that defines the "cards" you'd like to display on the page. The cards will
render in clickable boxes.
To get rid of this message and take advantage of this template, define `cards`:
```yaml
---
cards:
- progression: no
- card:
title: Mean Stack
image: /docs/meanstack/image_0.png
description: Lorem ipsum dolor it verberum.
- card:
title: Guestbook + Redis
image: /images/docs/redis.svg
description: Lorem ipsum dolor it verberum.
- card:
title: Cloud Native Cassandra
image: /images/docs/cassandra.svg
description: Lorem ipsum dolor it verberum.
- card:
title: WordPress + MySQL
image: /images/docs/wordpress.svg
description: Lorem ipsum dolor it verberum.
---
```
**Note:** If `progression` is set to `yes` then a "Start Here!" icon will be
placed on the first card and arrows suggesting linear reading will be overlayed
between the other cards, telling the reader that they should explore the content
in a certain order.
