Hi,
It would be nice to have the chart published in a repository so it's easy to use OOTB.
Hosting a repository is pretty straight forward with github pages feature.
There is a guide here https://helm.sh/docs/topics/chart_repository/#github-pages-example .
Took me about 1h to setup if I recall.
You can check what I did here and take what you need: https://github.com/ieugen/charts .
Also adding the helm repository to artifacthub.io is very simple after that.
Just sign in to artifacthub, then go to user menu (top right) / Control panel and then Add repository.
Put the same url you would use to helm add
