-# The SCS website project
+# The old SCS website project
 
 The static [SCS website](https://scs.community) is generated by [Jekyll](https://jekyllrb.com/). The theme is originally based on the template [business-frontpage](https://github.com/sharu725/business-frontpage) by [sharu725](https://github.com/sharu725). We're heavily making use of [Bootstrap 5](https://getbootstrap.com/docs/5.0) to layout the page content.
 
 The website is automatically built every 15 minutes or on every push to `main` and subsequently pulled onto our webspace.
 
+**NOTE: This repository is no longer used and we no longer build our old web site from it. Please go to
+[our new site](https://sovereigncloudstack.org/).**
+The content will be archived and remain accessible for historical reasons.
