 ## Features
 
 - easy to backup, everything saved in one SQLite database
   - also export feature in the frontend
-- [WebDAV Push](https://github.com/bitfireAT/webdav-push/) support, so near-instant synchronisation to DAVx5
+- 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)
 - deleted calendars are recoverable
 - Nextcloud login flow (In DAVx5 you can login through the Nextcloud flow and automatically generate an app token)
 - Apple configuration profiles (skip copy-pasting passwords and instead generate the configuration in the frontend)
-- OpenID Connect support (with option to disable password login)
+- **OpenID Connect** support (with option to disable password login)
+- Group-based **sharing**
