 This operator helps you to manage (self-)hosted databases in your Kubernetes clusters by defining them with [Custom-Resources](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/).
 It will automatically handle creation, updates & removal of your external databases.
 
-> __Example:__ You are deploying a guestbook web-application. For the app you need some kind of deployment, a service, an ingress route and a database.
-As you do already have an external database system hosted outside Kubernetes you only want an automatic generation of a new database in that system with a new user for your application.

 This can be done with the following manifest:
 
 ```yaml
-apiVersion: rzab.de/v1
+apiVersion: anbraten.github.io/v1alpha1
 kind: Database
 metadata:
   name: guestbook-database
 spec:
-  type: mysql
+  type: mongo
   database: guestbook
   username: guestbook-admin
   password: iwonttellyou
 ```
 
-> Important note: :rotating_light: Database types can not be updated! Updating the user credentials normally results in recreation of the complete user which could delete your custom changes.
+> Important note: :rotating_light: Database settings (`type`, `database`, `username`, `password`) will possibly re-create the corresponding data and wont migrate the database or user.
