 Design and feature inspiration taken from [KoInsight](https://github.com/GeorgeSG/KoInsight) - an excellent alternative that focuses more on statistics and also supports acting as a KOReader sync server. If you're primarily interested in reading stats rather than highlights and annotations, definitely check it out!
 
+The calendar feature is powered by [EventCalendar](https://github.com/vkurko/calendar) - a lightweight, full-featured JavaScript event calendar library.
+
+Styled with [Tailwind CSS](https://tailwindcss.com/) for modern, responsive design.
