+## Redis Sentinel configuration
+
+When using Redis Sentinel for high availability, enable failover mode and provide the sentinel master name. Multiple sentinel addresses can be specified as a comma-separated list in the `redisHost` field for redundancy.

 4. Next, we'll get our Redis password, which is slightly different depending on the OS we're using:
     - **Windows**: Run `kubectl get secret --namespace default redis -o jsonpath="{.data.redis-password}" > encoded.b64`, which will create a file with your encoded password. Next, run `certutil -decode encoded.b64 password.txt`, which will put your redis password in a text file called `password.txt`. Copy the password and delete the two files.
