Looking good so far only a couple of comments.

[christopherhein]

Maybe above this section, we can add a note saying to run kubectl get cluster -w and wait for the Status to say Ready.

[nobody4t]

Can we just say:

This error means that the status of the cluster is not ready. Please wait until the cluster is ready and try again.

[jichenjc]

kubectl get cluster -w

the status stuck at

NAME             PHASE
cluster-sample   Provisioned

for long time..

[jichenjc]

it should be running per cluster-api project
I guess some pre-requirement not complete so status of cluster is not running ...need find reason later on

[christopherhein]

Yeah, there was a bug with the published version actually :/ so that object doesn't get updated properly, I fixed it in #136 maybe we can use kubectl get nestedcluster -w instead since that updates properly and then when that other PR is merged we can switch this back to the cluster resource.

Nice job on the updates, if you could just get a couple more pieces in place this will be good to go.
👍

My concern about the # is a lot of people copy and paste and this is commonly a comment character.
