+## oe7drt.com
+
+This is the content and some modified theme files that create
+my personal website on `oe7drt.com`.
+
+The domain name is actually my callsign -- which we use in
+amateur radio.
+
+### Build tools
+
+I write content and code with Neovim (AstroNvim). Hugo puts it then
+together and builds a website out of it.
+
+The final website is pushed to my webserver via rsync.
+
+The code and content is saved on my own Forgejo instance on my homeserver.
+It gets mirrored to the codeberg repository.
