Run helm lint <chart-dir-name> to check for errors.
If there are no errors, run helm package <chart-dir-name>. This will create a .tgz file named <chart-name>-<chart-version>.tgz.
This file should be copied to this repo.
Lastly, the repo needs to be reindexed. This can be done by running helm repo index . --url https://bigstepinc.github.io/bdl-charts-repo.
Note: Also adding the chart files to this repo is not recommended, as it might produce versioning problems.
