+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application

+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)

+Your Duino-Coin miner DaemonSet has been successfully deployed!
+
+Since the miner does not expose any HTTP service, there is no application URL.
+
+To check that it is running on all nodes, use:
+
+  kubectl get daemonset -n {{ .Release.Namespace }} {{ include "duino-miner.fullname" . }}
+
+To view logs from one of the miner pods:
+
+  kubectl logs -n {{ .Release.Namespace }} -l app.kubernetes.io/name={{ include "duino-miner.name" . }} --tail=50 -f
+
+To see which nodes are running the miner:
+
+  kubectl get pods -n {{ .Release.Namespace }} -o wide -l app.kubernetes.io/name={{ include "duino-miner.name" . }}
+
+Happy mining!
