-### Global and role-specific default connection parameters ###
-
-While the `parameters` client option is useful to apply a set of default parameters and their values
-to connections created by the underlying connection factory, sometimes it is useful to set different
-values depending on the actual role of the target node (just to make an example, for sentinel nodes
-it is common to use a lower connect() timeout compared to the default value for normal Redis nodes).
-To make this possible `parameters` allows passing role-specific default values as named arrays using
-three special keys: `role.sentinel`, `role.master` and `role.slave`. These role-specific parameters
-take precedence over global default parameters passed at the root level of `parameters` but they do
-not override parameters explicitly set by the user for each single node just like global defaults.

-When master and replica nodes are configured to require authentication from clients, users must pass
-`password` (password-based authentication) or `username` and `password` (ACL-based authentication on
-Redis >= 6.0) via the global `parameters` client option.
+If the master and slave nodes are configured to require an authentication from clients, a password
+must be provided via the global `parameters` client option. This option can also be used to specify
+a different database index. The client options array would then look like this:
 
 ```php
 $options = [
