[#]# v0.2.0
  [#]## Added
- `mirror inspect-images` flag `--output` usage updated, flag `--file-name` no longer needed.
  - `-o file=filename`
  - `-o json=filename.json`
  - `-o yaml=filename.yaml`
  - `-o skopeo=filename.yaml`
- `helm-mirror` has a new flag `--new-root-url` new root url of the chart repository.
  (eg: `https://mirror.local.lan/charts`). This will allow users to set the name of

[#]# v0.1.0
  [#]## Added
- `mirror [chart-repo] [target-folder]` this command takes a chart repository and downloads all
  chart found in there and downloads them to a local target folder.
- `mirror inspect-images [target]` this command takes the target and extracts all container
  images being used in it. It can be a single chart or a folder with multiple charts. If
  some values are not present to process the chart you can use `--ignore-errors` flag to
  render the charts and get the container image anyway. (this can output inconsistent data)
- Use Helm configuration settings for Chart Repository.
