-For full documentation visit [mkdocs.org](https://www.mkdocs.org).
+After having my old site sit dormant for the best part of five years, I think it's probably
+finally time to try something a bit different. For a start, I've ditched Wordpress; in part 
+because of the unending tantrums of Matt "Drama" Mullenweg, but mainly because Wordpress is
+just overkill for what I need (as well as being constantly attacked.)
 
-## Commands
+This new site is based on [MkDocs](https://www.mkdocs.org/) and [MKDocs Material](https://squidfunk.github.io/mkdocs-material/)
+and automatically builds when I push the git repository containing the source files. I'll 
+be describing the setup for that soon, as well as talking about my current work in progress
+game [Project Shinar](https://jeremiahfieldhaven.itch.io/project-shinar).
