@peterzhuamazon @DandyDeveloper @smlx Have a look a this cleaning when free. Thanks

No issues, but why out of interest?

Perhaps update the README as well since we have the chance?

Yes @TheAlgo probably we can just add a simple README within the helm-charts folder and explain why we deprecated this part and more to helm-charts repo?

Thanks.

@peterzhuamazon @DandyDeveloper I agree but wanted to understand why we want to keep the helm folder lying here and create confusions. People may land to this repo and install the stale chart and create issues onto that. IMO deprecation is not a good word to describe the initial chart since it was WIP. We just moved our code.

But yeah if everyone else agrees on not removing the folder I can change the behaviour.

[IMO]: Also if we have a submodule in future this can also serve as an index , since everyone can make a PR to create a new tool or facility for deploying OpenSearch stack starting from here.
