 Since Redis can return FQDN of nodes in reply to client since `7.*` with CLUSTER commands, we can use cluster feature with SSL/TLS connection like this:
 
 ```ruby
-Redis.new(cluster: %w[rediss://foo.example.com:6379])
+Redis::Cluster.new(nodes: %w[rediss://foo.example.com:6379])
 ```
 
 On the other hand, in Redis versions prior to `6.*`, you can specify options like the following if cluster mode is enabled and client has to connect to nodes via single endpoint with SSL/TLS.
 
 ```ruby
-Redis.new(cluster: %w[rediss://foo-endpoint.example.com:6379], fixed_hostname: 'foo-endpoint.example.com')
+Redis::Cluster.new(nodes: %w[rediss://foo-endpoint.example.com:6379], fixed_hostname: 'foo-endpoint.example.com')
 ```
 
 In case of the above architecture, if you don't pass the `fixed_hostname` option to the client and servers return IP addresses of nodes, the client may fail to verify certificates.
