+- **[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](setup/oidc.md) support (with option to disable password login)

+
+### Authentication
+
+Authenticate with HTTP Basic authentication using your user id and a generated app token.
+
+## `/caldav` vs `/caldav-compat` (relevant for group sharing)
+
+To discover shared calendars the `calendar-home-set` property is used to list all principals the user has access to.
+However, some clients don't support `calendar-home-set` containing multiple paths (e.g. Apple Calendar).
+
+As a workaround `/caldav-compat` offers the same endpoints as `/caldav` with the only difference being that it does not return all calendar homes in `calendar-home-set`.
+This means that clients under this path will probably not auto-discover group calendars so you can instead add them one-by-one using the principal path `/caldav-compat/principal/<principal_id>`.
+
+## DAVx5
+
+You can set up DAVx5 through the Nextcloud login flow. Collections including group collections will automatically be discovered.
+
+## Apple Calendar
+
+You can download a configuration profile from the frontend in the app token section.
+
+**Note**: Since Apple Calendar does not properly support the `calendar-home-set` property the `/caldav-compat` endpoints should be used.
+That also means that Apple Calendar is not able to automatically discover group collections so in that case you'll have to manually add all principals with `/caldav-compat/principal/<principal_id>`.
+
+## Evolution
+
+Set up a collection account in the account settings.
+Evolution correctly uses all calendar homes so group collections work properly.
+
+## Home Assistant CalDAV integration
+
+The underlying library `python-caldav` does not support multiple calendar homes so you should use the `/caldav-compat` endpoints.
+
+As URL specify
+
+```
+https://<your-host>/caldav-compat
+```
+
+For group collections explicitly specify
+
+```
+https://<your-host>/caldav-compat/principal/<principal>
+```
+
+## Thunderbird
+
+- Go to `New Account -> Calendar -> On The Network`
+- Specify the root path of RustiCal
+- Thunderbird will properly discover group calendars
