+# Jangle CMS
+> An example web app made with Elm
 
+## Introduction
+
+In August 2023, I took a gap year and started to build a CMS using [Elm Land](https://elm.land). I got pretty far
+with the design system and made a lot of Elm components, so I thought it would be fun to share the source
+code for the design system at [https://design.jangle.io](https://design.jangle.io):

+
+Feel free to take whatever you want from this project, I hope it helps you or your business make cool things
+with Elm! :heart:
