Locate your Chart.yaml file in your Helm chart directory. This file contains metadata about your chart including name, version, and dependencies. Copy the contents of the file.

Paste your Chart.yaml content into the editor. The validator automatically checks for syntax errors, missing required fields, invalid values, and compliance with Helm best practices. Validation happens in real-time as you type.

Check the validation results in the right panel. Errors must be fixed before deploying your chart. Warnings indicate best practices that should be addressed. Suggestions help improve chart quality and discoverability.

Once validation passes, download your corrected Chart.yaml file. Save it back to your chart directory, then package and deploy using helm package and helm install commands.
