 1. Install Redis into your cluster: `helm install stable/redis --name redis --set image.tag=5.0.5-debian-9-r104`. Note that we're explicitly setting an image tag to get a version greater than 5, which is what Dapr' pub-sub functionality requires. If you're intending on using Redis as just a state store (and not for pub-sub), you do not have to set the image version.

 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.
