+  While I've been successfully using RustiCal productively for some months now and there seems to be a growing user base,
   you'd still be one of the first testers so expect bugs and rough edges.

+  If you still want to use it in its current state, absolutely feel free to do so and to open up an issue if something is not working. :)
 
 ## Features
 
 - easy to backup, everything saved in one SQLite database
   - also export feature in the frontend
+- Import your existing calendars in the frontend
 - **[WebDAV Push](https://github.com/bitfireAT/webdav-push/)** support, so near-instant synchronisation to DAVx5
 - lightweight (the container image contains only one binary)
 - adequately fast (I'd love to say blazingly fast™ :fire: but I don't have any benchmarks)
