+# New User Documentation Site
+
+Starting in 2026, we are changing the design of the user documentation website.
+Previously we had used the [documentation
+theme](https://github.com/tomjoht/documentation-theme-jekyll) together with the
+[Jykell SSG](https://jekyllrb.com/), but have now switch to the more modern
+[Material for MkDocs](https://squidfunk.github.io/mkdocs-material/) theme and
+SSG engine. This comes with a few improvements:
+
+* searching is more complete and provides better results
+* theme related improvements (day-night coloring, page layout, content formatting)
+* edits for pages can be submitted via the *Edit* (this will direct you to the Gitea repository which hosts the documentation)
+
+TBD
