These are the commands you will use most frequently.

the most useful command that i could find is preview . This helps to preview the kubernetes files that it creates 

helm template myapp ./helm/myapp -f ./helm/myapp/Chart.yaml 

this describes the kubernetes native files that are going to get generated.
