 RustiCal is **not production-ready!**
-I'm just starting to use it myself so I cannot guarantee that everything will be working smoothly just yet.
+While I've started migrating to RustiCal and becoming more confident, please know that bugs and rough edges will still occur.
-I hope there won't be any manual migrations anymore but if you want to be an early adopter some SQL knowledge might be useful just in case.
 If you still want to play around with 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
-- ~~[WebDAV Push](https://github.com/bitfireAT/webdav-push/) support, so near-instant synchronisation to DAVx5~~ (currently broken)
+  - also export feature in the frontend
 - 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)

+## User management
+
+In case you already have an OIDC server set up, see [here](setup/oidc.md) how to set up OIDC login and maybe skip this section.
+Otherwise you will have to use the `rustical principals` command.
+In Docker you can run this with
+
+```sh
+docker run --rm -it -v YOUR_DATA_DIR:/var/lib/rustical/ ghcr.io/lennart-k/rustical rustical principals
+```
+
+This is also the place to set up **groups**.
+Groups and rooms are also just principals and you can specify them as such using the `--principal-type` parameter.
+To assign a user to a group you can use the `rustical membership` command. Being a member to a principal means that you can completely act on their behalf and see their collections.
+**Note:** Many clients don't support autodiscovery of principals a user is a member of. In that case you'd have to set up multiple CalDAV profiles in your client with the respective principal URLs.
+
+## Password vs app tokens
+
+The password is optional (if you have configured OpenID Connect) and is only used to log in to the frontend.
+Since it's sensitive information, a secure but slow hash algorithm (`argon2`) is chosen.
+
+App tokens are used by your CalDAV/CardDAV client (which can be managed through the frontend).
+I recommend to generate random app tokens for each CalDAV/CardDAV client.
+Since the app tokens are random they use the faster `pbkdf2` algorithm.
+
 ## Configuration
 
-RustiCal can be configured using either a `config.toml` file or environent variables.
+While RustiCal (apart from user management) will work without any configuration you should still know how to configure it. :)
 
-To see all configuration options available you can browse the [Cargo docs](/rustical/_crate/rustical/config/struct.Config.html).
+You can either mount a `config.toml` file or use environment variables.

-You can generate a default `config.toml` configuration using
