+
+    I'd like to thank [@geertvanbommel](https://github.com/geertvanbommel),
+    a fellow software architect specializing in database batch processing and
+    API development, for sponsoring the first release! 🎉
+    Thanks to sponsors like this, who understand the importance of open source
+    development, I can justify spending time and focus on open source development
+    instead of traditional paid work.
+
+    > Did you know that I offer custom development services and issuing invoices for
+      sponsorships of releases and for contributions? Contact me (@clue) for details.
