-    Create a `values.yaml` file. Start with this minimal configuration that will get Digger running:
-    
-    ```yaml values.yaml
-    # Minimal configuration for initial setup
-    digger:
-      # Disable ingress for initial setup
-      ingress:
-        enabled: false
-      
-      # Basic authentication settings
-      secret:
-        httpBasicAuthUsername: "admin"
-        httpBasicAuthPassword: "changeme123"  # CHANGE THIS!
-        bearerAuthToken: "changeme456"        # CHANGE THIS!
-        hostname: "localhost"                 # Will be updated later
-    
-    # Enable built-in PostgreSQL for testing
-    postgres:
-      enabled: true
-      secret:
-        useExistingSecret: false
-        postgresPassword: "changeme789"       # CHANGE THIS!

-    <Info>
-      This minimal configuration:
-      - Disables ingress (we'll configure it later)
-      - Sets up basic authentication
-      - Uses built-in PostgreSQL for testing
-      - Gets you up and running quickly
