 * `servers`: A list of redis servers. If one is provided, it will be treated as a single instance, and otherwise, a cluster will be assumed.
 * `sentinel_service`: Lets you enable sentinel mode. When provided, the servers will be treated as sentinel instances.
-* `decode_credentials`: Indicates if server credentials (if present) should be URL decoded before passing to redis connection. Otherwise, they are passed verbatim.
 
 > **Note**
 > The entries in `servers` support credentials in the form of `tcp://password@my-server:6379` or `tcp://username:password@my-server:6379`.
