It was quietly open sourced earlier this week at an early state so we could start looking at importing it into something else (https://helm.sh v3). You likely will not find any examples, yet. It's not release quality quite yet so there will likely be changes as it becomes production quality.

I'm amazed people found this already. The team over there who owns this is excellent. I expect it to work nicely once they have had a little time to get everything together.
