Going thru https://helm.sh/docs/chart_template_guide/getting_started/

ls -R mychart/ mychart/: charts  Chart.yaml  templates  values.yaml

mychart/charts:

mychart/templates: configmap.yaml

trying to install the chart:

helm install full-coral ./mychart

but it fails with:

Error: This command needs 1 argument: chart name

Helm:

helm version
Client: &version.Version{SemVer:"v2.14.1", GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.14.1", GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}

Am I missing something obvious? Any help will be appreciated
