Chart names should be lower case letters and numbers. Dashes (-) are not allowed:
Chart names should use lower case letters and numbers, and start with a letter.
Examples:
Hyphens (-) are allowed, but are known to be a little trickier to work with in Helm templates (see [issue #2192](https://github.com/helm/helm/issues/2192) for more information).
Here are a few examples of good chart names from the [Helm Community Charts](https://github.com/helm/charts):
```
drupal
cluster01
aws-cluster-autoscaler #incorrect do not use dashes in the name
cert-manager
oauth2-proxy
```
Neither uppercase letters nor underscores should be used in chart names. Dots should not be used in chart names.
The directory that contains a chart MUST have the same name as the chart. Thus, the chart `nginx-lego` MUST be created in a directory called `nginx-lego/`. This is not merely a stylistic detail, but a requirement of the Helm Chart format.
