+## Architecture
+
+A thin plugin wrapper over [hijri-core](https://github.com/acamarata/hijri-core). The plugin augments the Day.js prototype with Hijri methods, each delegating to the registered calendar engine. Zero global state — calendar selection is passed per call.
+
+For more detail see the [Architecture wiki page](https://github.com/acamarata/dayjs-hijri-plus/wiki/Architecture).
