Themes can be categorised with terms from these 4 taxonomies. ssg, cms, css and archetype

If you are adding a theme which uses an SSG or CMS which doesnt exist you will need to add it as part of your pull-request.

1. Create a new taxonomy term by creating the markdown file under content/ssg/ or content/cms. For example let's say you wanted to add a new SSG called "Super Duper". Add a file under content/ssg/super-duper/_index.md and add the following frontmatter

---
title: "Super Duper"
icon: images/icons/super-duper.svg 
official_url: https://super-duper.org
---

2. Add the icon. You will need to upload an icon into static/images/icons. The icon should in SVG format under 3KB. If it's a PNG please make sure the size is 60x60px and the size is as small as possible (you should be able to keep it under 5KB)
3. Update the Javascript filter logic. Update the file themes/jamstackthemes/assets/js/filter/filter-groups.js and add super-duper to the ssg array.
