If we skip the TL;DR we should first install the CRDs here.

Was natsBox.enabled: false before and we'd add it later on with:
kubectl apply -f https://nats-io.github.io/k8s/tools/nats-box.yml
That file has been removed in the mean time, so instead just enable nats-box as part of our NATS installation.

Later on there are descriptions about:
First, we'll read the data using a pull-based consumer. In
consumer_pull.yml
we set:filterSubject: orders.receivedso that's the subject my-pull-consumer will pull messages from.
Saving it into a file makes it easier for people to inspect the contents when they get to this bit.

Now that nats-box is pre-installed, no need to install here and we need to refer to it by its deployment.

These would fail as by default (by now) the file system is read-only. Because we now enable nats-box above it's pre-configured and doesn't need a context to be set.
Update README with primarily two improvements:
