const installDescription = `If the given 'chart-name' is present in your workspace, it
will be uploaded into Kubernetes. If no chart named 'chart-name' is found in
your workspace, Helm Classic will look for a chart with that name, install it into the
workspace, and then immediately upload it to Kubernetes.

When multiple charts are specified, Helm Classic will attempt to install all of them,
following the resolution process described above.
