 The password for the mariadb database and the root password are generated randomly. A function is created in the `_helpers.tpl` file.  
 It's the same behavior for the matomo user password.
 
+The passwords won't change if you upgrade the Chart.
+
 Follow the instructions after deploying the Helm Chart to retrieve the passwords.
