+# Sets up a local Kubernetes cluster using Kind.
+# By default:
+#   - The cluster name is read from the `name:` field in the Kind config file (CONFIG_FILE).
+#   - cert-manager is installed automatically.
+#   - metrics-server is installed automatically (can be disabled).
+# Variables you can override:
+#   - CONFIG_FILE:        Path to your Kind config file.
+#   - CLUSTER_NAME:       Cluster name (overrides the name from the config file).
+#   - INSTALL_METRICS_SERVER: Set to false to skip metrics-server installation.
+# Usage examples:
+#   make setup-kind-cluster
+#   make setup-kind-cluster CONFIG_FILE=utils/configs/my-config.yaml
+#   make setup-kind-cluster CLUSTER_NAME=my-cluster
+#   make setup-kind-cluster INSTALL_METRICS_SERVER=false
