Tutorial steps are not valid for reproduction
I'm trying to learn how to use helm charts, but the information in the tutorial is misleading. I tried different ways to install helm chart from the repository but it doesn't work for me. It would be great to have an extra explanation where you get the required RELEASE_NAME and path for this step.

Hi, @antooa.
RELEASE-NAME is the name you want to give to that deployment to identify it. You can choose whatever you want.
The ./helm-chart/go-k8s/ path is the path to the Helm chart you created in a previous step.
Hi @alemorcuq and thanks for the reply.
I think the problem here is that directory ./helm-chart/ is already occupied by chart example.

I'm not sure if it's possible to create a chart inside the chart :)
I think the path should be ./go-k8s/ or even ./CHART-NAME/ so the learners could more easily understand the idea.
Anyway, thanks for the help.
So, in this case looking at your directory structure, your command should be:
helm install RELEASE-NAME ./helm-chart/
RELEASE-NAME can be whatever you want.
