+## Determining if we're in a subchart
+
+- `.Chart.IsRoot` indicates if we're in the top-level chart or in a sub-chart
+
+- Useful in charts that are designed to be used standalone or as dependencies
+
+- Example: generic chart
+
+  - when used standalone (`.Chart.IsRoot` is `true`), use `.Release.Name`
+
+  - when used as a subchart e.g. with multiple aliases, use `.Chart.Name`
