I was just chatting with @TerryHowe about trying out Promptless to help make it easier to maintain helm's docs. (I'm one of the founders, and a helm user.)
It seemed like this would be helpful for (1) maintaining translations of the docs in all the languages in i18n (sounds like this is the biggest pain point), and (2) detecting doc updates in general when PRs are opened in the helm/helm repo.
If you want to see how it works, we recently onboarded Vitess (another CNCF-graduated project), and you can see Promptless's commits in their docs repo in the last week.
Wanted to start a discussion about trying this out!
