This repository has multiple Github Actions to ensure quality is high, these include:

• helm-docs: check all chart README.md have all values documented
• helm-conftest: Ensures standard labels are present

All chart README.md files are generated from a template. This ensures all values are documented and that formatting is consistent. See here about how the table of values is produced and how to add descriptions to your chart values.
